This book deserves all the stars. I could not put this book down. Read it straight through in one sitting. It was everything I wanted and more for Xander. I fell in love with Xander the first time I read The Spare in 2023 and it has never gone away. Penelope and Xander complete each other in the most perfect ways. The banter! The chemistry! The spice!! They’re a perfect balance and the marriage of convenience of it all is the perfect trope for them. The friendship and found family in these books is SO FRICKIN GOOD TOO!! It’s absolutely all around a 5💫 book for me.

Ava knocked it out of the park for this third installment of the series. I am so excited to read everything she writes, she is an autobuy author for me!! Thank you to NetGalley and HarperCollins publishers for the ARC!!

Does these kind of men actually exist?? If so please show me the way. It's rare to read a book where the MMC loves the FMC since the beginning of the book, and it actually turns so good. There relationship is so healthy and their communication is excellent. If only it has less spice it'd have been a 5 stars

Ummmm, guys, I requested books 2 & 3 of the Biotech Billionaires series from Netgalley -big thanks to them & Avon and Harper Voyager - and just got approved for this one, guess I'll run to borrow the 2nd 🏃🏻‍♀️

A fun, easy read and my favorite book of the series! Penelope Chen-Astor is looking to claim her inheritance but in order to get it she needs to be married to someone of her family’s choosing. Refusing to be controlled like a pawn in her family’s game, Penelope looks for another option to gain some semblance of control—enter Xander Sutton who’s been smitten with Penelope since the moment he saw her.

Penelope and Xander are the perfect balance as a couple—she’s more reserved whereas he’s playfully charming. I’m a sucker for “he falls first” & any marriage of convenience trope and this book serves it all! The pacing of the plot was just right, and I loved how Xander and Penelope were just mature adults that didn’t act on at childish impulses. I was happy that there was no third act breakup and how they resolved conflict as a couple. That in itself felt truly refreshing!

Thank you again to NetGalley and Avon/Harper Voyager for a chance to read an advanced copy of this book, and give an honest review!

Welp, I'm happy and devastated at the same time. Happy because all of the crew got their happily ever after but devastated because I'm not ready for it to be over! I am slightly pacified by the fact that Ava has said she's working on something and I'm holding out it's a spinoff!!

After devouring the Spare and the Heir, I was really looking forward to the Charmer, knowing it was Xander's story. He was absolutely worth the wait!! Xander has always been the one that wants to see everyone else happy, maybe even pulling some of the strings for the others without their knowledge! He's always the one giving to others, and I was so excited to see him take a chance and embrace the feelings he'd been harboring for Penelope!

After seeing her only as a side character in the previous books, it was so nice to get to finally understand Penelope. She always seemed so buttoned up, and hesitant to "let her hair down" as it were. NOW WE KNOW WHY. She's always been dedicated to her friends, but this book really let us see just how dedicated her friends are to her. How they pulled together to help and protect her (lead by our leading man) made for a great story!

Per usual, Ava's writing had me giggling one moment, sighing dreamily another and always reading way too fast. The funny moments are always just so real, and the sweet ones create the perfect level of angst. All in all, I loved Xander and Penelope's story and will be anxiously waiting for anything else that might be coming from this world!!

Massive thank you to the team at Avon and the author, Ava Rani for the eARC!

While I am sad to be finishing this series, I couldn't think of a better way than to end with the love story of Xander and Penelope. Seeing our goofy and fun loving prankster Xander fall in love and do everything in his power to make sure Penelope was happy just made my heart smile. Seeing the passion grow between them and ultimately just the love that they shared made it a little less hard to stay goodbye to my Biotech Billionaires. Ava, your writing is just so well that I could picture the events like I was watching them unfold infront of me. I'm so proud of you and this series 💜

this was a pretty good book! I think it was a book with a lot going on and it did feel messy at times. I think the storyline could have been a bit clearer and flowed in a smoother manner.

Thank you to NetGalley, to the author, and to the publisher for this complimentary ARC in exchange for my honest review!!!

What a perfect way to end the series! Of course, I'd prefer if the series didn't end at all, but oh well :')

Xander and Penelope are my favorite couple of the series, which is crazy because I always think there's no way Rani can top her previous couple. Those previous couples make frequent appearances, which makes me so happy! Our main characters fit so well together, and I love how they helped each other with their issues while still giving each other space to grow separately. Seriously one of the healthiest relationships I've ever read.

I absolutely love this book, and I can't wait to see where Ava Rani goes next with her writing. Thank you to the publisher for the e-arc. All thoughts and opinions are my own.

had the extreme luck of receiving an ARC from @netgalley and I am in love!!!! It’s so good and I need my preordered copy to arrive as soon as humanly possible.

Ava Rani’s entire Biotech Billionaires series is amazing and I highly recommend them!

Xander and Penelope are amazing. I love how open they were. While this is a marriage of convenience, it’s adorable how they come together.

This whole book had me kicking my feet and giggling. I also love the underlying “pick me because I’m worth it and deserve it not because you want love or a person” which hit so hard and made this book even more amazing.

Obsessed does not even begin to describe it. This book has me in a chokehold that I’m thinking about days later. I love this world Ava created but even more I love Pen and Xander. Their relationship is one of fairytales and I am obsessed. They’re so loving and kind, but talk through so many hard subjects. Ava perfectly captures what it feels like when you find your person and I loved every second of it.

Great billionaire romance! I need to read books 1 & 2 asap!

Thank you Avon and Harper Voyager fir granting me an ARC!

Billionaire romance but they are both billionaires okkkayyy 💅🏼 we love a strong fmc! Penelope is an attorney who needs a marriage to get not only her inheritance but her mothers as well yet obvs she doesn’t wanna until my man Xander steps in because he’s such a good guy! Fake dating faking marriage Xander and Penelope always had eyes for each other I loved Xander more than Penelope. I love that the couple is not white like hell yeahhh let’s show some bipoc love. The romance is to die for however it is heavy on tech/business law lingo so that flew over my head overall everything was great I just wish I would’ve read the first two books before this one.
Thanks NetGalley for the arc

Big shout out to Net Galley for the eARC of this book. I hate to say it but this is my first book by Ava Rani and I was thoroughly surprised! Although I know (or more so figured out as I was reading the book) that this was the last book in the series, I didn’t feel completely lost with Xander and Penelope’s story. The book was a good mix of a marriage of convenience and ‘he fell first’. The way that Xander took care of Penelope, made sure that she was able to complete everything on her “list” and listened to her needs was majorly swoon-worthy. However, I will say that the business aspects of the book kinda flew over my head and I didn’t pay as much attention to it as I probably should have, but all in all, it was an amazing read! I’m excited to read more from Ava Rani.

Oh, my yes! A billionaire romance that is undeniably captivating, balances sleek and sexy excess with humor and warmth, oozes power laced with good intentions, and serves up a love story that feels lush, vibrant, and heartachingly pure. There is one hundred percent a reason Xander Sutton is called the charmer, it’s splashed across every page of this read, and you are more than happy to fall for all of it and beg for a little more.

Just an incredible read with divine characters that tug heart strings, offer emotional depth you can’t help but connect with, and burrow right to your soul. The story itself feels decadent, sexy, and touching, and the significance of Xander and Penelope's relationship, what it means for Xander and to his family, deepens every aspect, makes you love it more, and turns a marriage of convenience into the moment a broken, heart hidden behind layers of protective armor, terrified man, finally became whole and healed, and it’s simply stunning.

Thank you to the author, Ava Rani, and to the Avon team for access to an Advanced Reader Copy of The Charmer, the last book in Ava's Biotech Billionaire series! Ava writes diverse, high society romances so well and Xander and Penelope's love story is no exception.

Xander is known for being a charming, outgoing billionaire co-founder and Penelope is known for being a respectful, reserved high-powered lawyer. Their personal and professional circles overlap, but their one-on-one time has been quite limited yet rather impactful.

One inheritance stipulation and marriage of convenience later, they are together more than ever and it's sweet to see how they come to act naturally around one another instead of acting as others expect them to. Those who often play the role of the responsible one or the charismatic one will find relatability in our two main characters! It’s very sweet and satisfying to see them become unguarded and unfiltered with each other.

Xander is a man DOWN BAD and I loved the ways this came through in his sweet and spicy dialogue with Penelope <3 It was so fun to see Xander try to wrangle the main couples from Books 1 and 2...and to learn how he played matchmaker to help Henry and Marcus get the girl behind the scenes…

My favorite element of this story was the pair’s sweet simmer from fleeting, chemistry-filled moments to deep appreciation and strong understanding of one another, leading to an excellent foundation for a friendship and a marriage :’)

I highly recommend reading Ava’s entire Biotech Billionaire series in order (starting with The Spare) to fully enjoy this found family friend group. Thank you to Ava for creating beautiful multicultural love stories for us to enjoy!

Thank you to Avon & Harper Voyager and NetGalley for the advance reader copy of The Charmer by Ava Rani!

Penelope Chen-Astor is a Manhattan lawyer. It’s been expected that she would marry Maddox, which would fulfill her grandfather’s will demands to get her inheritance. When faced with marrying Maddox, who conveniently steps in to play the part of fiancé but Xander Sutton? Xander agrees to a marriage with Penelope but will the two be able to resist a fake marriage becoming real?

What an incredible conclusion to the Biotech Billionaries series! I love that Ava Rani’s books are so rich in romance but also the depth of story beyond the romance. I was so excited when the book for Xander was announced. I was so excited to read Xander’s story but also was so excited that it would be a marriage of convenience story - one of my FAVORITE tropes! I loved the setup that brings Penelope and Xander together and the pining in their POVs. I melted when these two get together.

It’s also so wonderful to get to see and check in with the rest of the characters - Sloan, Marcus, Henry, and Selena. If you enjoy a marriage of convenience and billionaire romance, this is a book and series to check out!

With no third act breakup, a fake marriage and a man who’s loved her for agessss and she’s a billionaire too?! Yes please, this book has everything I want in it! It was just good true romance, Penelope is a closet freak which I loved and they were such a good team. I’ve loved all the books in the series and this was another great book!

This is my favorite in the series and it was so cute and so steamy. I've been waiting for Xander's book since I started indie reading this series, which did not disappoint. Xander and Penelope were everything to me, my cute babies. In the beginning, they were just friends with a little bit of he fell/liked her first, which led to a marriage of convenience. I love that some of the book takes place in Singapore and Europe and the descriptions of the places were beautiful. The romance was so good and let's just say there's a list of things(including steamy things) Penelope wanted to do that Xander made sure to do with her. Xander was such a great and emotional character and I loved how strong both main characters were.

I loved the billionaire and business aspect of the book along with seeing all the characters from the other books. The plot kinda reminded me of the show Suits and the drama that came with taking down businesses and law. I loved seeing all the main characters from the rest of the series being in love and crazy about each other while still being strong bosses. Lastly, I loved how I could see that the author's writing has kept improving since her debut and I just really enjoyed the writing and the flow of the book. Thanks to Avon for this arc for an honest review.

Read for:
- Diverse romance
- Billionaire mc's
- Tight-knit friend group
- Business and law drama
- Steamy list

The Biotech Billionaires series has been an unforgettable journey, and I’m heartbroken to see it come to an end. Ava Rani has once again delivered a masterpiece with The Charmer, showcasing her incredible ability to craft complex characters, heartfelt relationships, and a story that keeps you hooked from start to finish.

Xander and Penelope are absolute perfection together. Their relationship feels so real and layered—Xander’s transformation when he’s with Penelope is particularly moving. Gone is the goofy, carefree persona; instead, we see a man who truly understands and cherishes Penelope. He steps up in ways no one else in her life ever has, and it’s so satisfying to watch him become her rock after everything she’s endured with her cruel and unsupportive family.

The friendships in this series, especially the bond between Sloan and Xander, are another highlight for me. They bring so much warmth and authenticity, adding depth to an already rich narrative. The found family dynamic among all the characters is one of my favorite aspects of the series—it’s a beautiful reminder of how the people we choose can become our true family.

This book gave me serious Crazy Rich Asians vibes, and I was all in for the glitz, glamour, and drama. Ava Rani has mastered the marriage of convenience trope here, blending it seamlessly with the black cat/golden retriever dynamic that’s both heartwarming and fun.

It’s rare to find a series that stands out the way this one does. The Biotech Billionaires books have been my favorite reads, and The Charmer is the perfect finale to this phenomenal journey. Mark your calendars for May 13th—this book is not to be missed! Ava Rani has cemented herself as a must-read author, and I can’t wait to see what she has in store next.

The Charmer is the kind of romance that sneaks up on you in the best way. Penelope is tough as nails and smart, but you also get to see her softer side, especially with Xander, who starts out as just her marriage of convenience but quickly becomes so much more.Their chemistry is fire from the start, and the way they navigate family drama and their growing feelings for each other was just chef’s kiss. It’s not just the sizzling romance; there’s depth, emotional pull, and the tension is off the charts. From start to finish, this romance had me hooked, and I couldn’t get enough of Penelope and Xander.

I received this book from Netgalley and here are my honest thoughts. How I wish I had known about this series earlier. This is a billionaire romance written by a BIPOC author with diverse characters and locations. Penelope who is half Singaporean and apparently British royalty has a marriage of convenience with Xander. (Frankly, the best way to shorten Alexander). Xander is a billionaire and a friend who has been crushing on Penelope for quite a while and he finally gets a chance to be a presence in her life. I loved the fact that Xander seems to be a truly nice guy who wants to care for others. Penelope is a true elder child who is bearing the weight of her family’s expectations and is trying to find freedom. We travel from Manhattan to Singapore and many other lovely places in this global book. There are plenty of billionaire shenanigans we all love like expensive purchases, private jets, corporate espionage, and a black card. I could eat it up with a spoon. The story has an interesting plot and a lovely slow burn. 🥵There is a “found family” trope which is my favorite and two epilogues!! No notes. A fun and satisfying read.
