I love the Costa family! Alessandro and Calliope have an unconventional start to their relationship, but I really enjoyed going on their journey with them.

This book is an absolutely captivating read that left me spellbound from beginning to end. The author masterfully creates a rich, immersive world where magic and adventure leap off the page, and the depth of detail in the world-building is truly remarkable.

The protagonist, is a beautifully complex character whose journey of self-discovery and courage resonates deeply. Her growth throughout the story is both believable and inspiring, making her a heroine you can’t help but root for. The supporting characters are just as well-crafted, each bringing their own unique charm and depth to the narrative.

The plot is filled with twists and turns that kept me on the edge of my seat. Just when I thought I had figured out what would happen next, the author skillfully surprised me. The themes of friendship, sacrifice, and the fight between good and evil are woven seamlessly into the narrative, adding layers of meaning that will leave readers pondering long after they turn the last page.

Overall, is a must-read for fantasy lovers. I can’t wait for the next installment!

I started the book today and I couldn’t stop reading it. I loved how Brittney gave us details about our Dublin Nights family and seeing even Ella pop up in the book. This book was brilliant, amazing, exceptional. I don’t know what more I could say but I love the Costa family.

Why am I not surprised that Brittney has gone and done it again... this book was Amazing!!! I fell in love with Alessandro and Calliope from the very beginning. The chemistry between these two is HOT! Alessandro has a playboy reputation but when he lays eyes on Callie and they start talking and she gives him sassy comebacks the sparks fly. Brittney weaves a masterful story with adventures involving some of our favorite, lovable characters from previous books. I could not put this book down... it's probably one of my top 3 books of Brittney's and I've read all of them!

I received this book in exchange for a review:
1000 stars!
Brittney you have never cease to amaze me with you books, I can always count on losing myself in your stories and be left wanting more 😍

Alessandro and Callie have off the charts chemistry when they first meet, but wowzers are they scorching once they have to "work " together! Just as all her other books, Brittney makes you think you know her next move, but you're still completely surprised at her next move... I'll never tire of your books girl!!

I absolutely love when she ties her other characters in from her other stories... love seeing them return, even if just for a short bit!

Another fantastic story by Brittney Sahin! This is the next installment of The Costa Family series. ** This can be read as a standalone, but reading the prior books in the series will help with knowing the family dynamics.** Alessandro is sent to Tennessee for an unknown mission. It turns out that he is to not only protect but marry Calliope (aka Callie), who is the daughter of a Mafia boss. Alessandro is not the marrying kind, but as he was indebted to the requestor he agrees with the plan. This story has many twists and turns and reacquaints the reader with characters from some of Ms. Sahin's previous books. This is a very well written book that will have the reader turning pages in anticipation of what will happen next. Highly, highly recommended!
I received an advance review copy and received no compensation for this review.

LOVE, LOVE, LOVE! Once again Brittney Sahin brings it. Five Stars! I absolutely fell in love with these characters and the story line is so good. Keeps you wanting more. Her books are chalked full of interesting plots and spicy romance. Swoonworthy male characters and strong female characters . You can not go wrong with any of her books.

I don’t know how Brittney does it, but she knocked it out of the ballpark once again! Not Mine to Keep is the second installment in the Costa family series, and I just loved the whole storyline! ❤️ It has everything you could want in a romantic suspense novel (action, adventure, humor, spice, family drama, love, and more)! 😍 Brittney is an amazingly gifted writer, and you won’t want to miss her latest masterpiece!! ✨

Brittney's books never disappoint, the perfect amount and blend of suspense, intrigue, and romance! I love that she incorporates characters throughout her different series and how seamless she integrates these "guest appearances." Not Mine To Keep follows Alessandro and Callie who marry hastily in an attempt to thwart Callie's mafia dad and his attempt to control her and get an heir out of her. Their blossoming romance, even knowing the marriage was not real, is so fun to follow!

I was obsessed with Alessandro and Calliope from the very beginning. The way they met, the instant flirting, the "job" that came out of everything was very meant to be.
I have read most of Brittney Sahin's books and it was so fun to see characters from other books come into this book. (You do not need to read her other books to understand this story, but it helps!) The quick reference to Ella, and her designs was my absolute favorite!
In the beginning Alessandro was getting on my nerves, but I know he had a reason to act the way he did. Brittney did a wonderful job of a slow burn, while also keeping the book spicy! The dark elements in this book were also *chef's kiss*! Alessandro's mask....perfection.
I loved everything these characters went through and I love that they were both able to grow from each other.
Now I am patiently waiting for Hudson and Constantine to have their turn!
10/10 would recommend! Thank you Brittney for another AMAZING read!

I couldn't put this book down - I always find myself lured in to the connection of the main characters right from the start with Brittney's writing. Love the balance between suspense and romance.

"Not Mine To Keep" is a brilliantly crafted tale that brings together two characters from vastly different worlds—Alessandro Costa, a billionaire playboy, and Calliope Dawn Anderson, a school teacher with a hidden talent for singing. Known to her mafia family as Calliope DiMaggio, the Mafia Princess, she faces a life far removed from the ordinary. From the outset, the reader is drawn into the complex journey these two must navigate, witnessing how they both guard their hearts despite the undeniable chemistry that sizzles between them.

True to Brittney Sahin’s signature style, the story is a gripping blend of intense passion, emotional turmoil, and electrifying chemistry that keeps you hooked from start to finish. The plot is full of unexpected twists and turns, keeping you on edge until Alessandro and Callie finally reach their much-deserved happily ever after. Callie’s fiery personality and Alessandro’s steadfast loyalty stood out as highlights, making their romance all the more engaging.

What I particularly enjoyed was how Brittney seamlessly weaves in glimpses of the characters’ backstories, adding depth and a sense of realism to the narrative. It's always a treat to get a little update on some familiar faces from past stories. Overall, Brittney Sahin has delivered yet another remarkable book that’s sure to resonate with fans. Bravo!

I received an ARC of this book, and let me tell you that Brittney Sahin has done it again!

Alessandro Costa, a "lifelong bachelor" and Calliope aka Callie, a history teacher and musician, meet at an auction, and their chemistry is off the charts from that moment. They try to deny their attraction and feelings for one another, but eventually, they give in, and then life happens.

I love Callie and Alessandro. They are so good for each other, the chemistry, the banter, the love, this book has it all.

I've read a lot of these authors' books, and I can't wait for the next release! Her stories have me sitting on the edge of my seat, in tears, giggling, or staying up late because I can't put it down! (Alessandro has even made my book boyfriend list!*swoon*)

This book contains......
Romance, suspense, action, Mafia, age gap, forced proximity, marriage of convenience/arranged marriage, "retired" military, opposites attract....Just to name a few 😉

Another incredible read! Each book by Brittney is a journey into a fascinating world with suspense, danger, a web of intrigue and sizzling romance which all come together in an addictive experience.

The Costa family is a newer layer in the broader world that Brittney has created, but I love how well they fit with beloved characters and other storylines. Alessandro was determined to never marry, but when his former best friend cashes in a long owed favor he has no choice and little resistance for his bride-to-be.

Calliope/Callie is a sassy, intelligent and stubborn woman who recently discovered her biological father is the head of a Sicilian crime family. When she learns his recent illness has amped up his determination for her to have an heir for his empire, she’s forced to marry a sexy man she just met and isn’t sure she can trust.

The relationship is completely unorthodox, but it’s thrilling and suspenseful with lots of unexpected surprises.

I have loved everything this author has written and I’m excited about the next book in the series featuring Izzy and Hudson.

I received a free ARC from the author; and I am voluntarily leaving an unbiased review.

Alessandro and Callie were hot from the minute go and despite not wanting to feel anything for each other, they stayed hot! Battling together against her father and the threats he created while he also worked with his family to take down one of their enemies resulted in lots of exciting and heart stopping action and also the realization that they belonged together. He became her biggest fan and she healed his broken heart. Not Mine To Keep was yet another piece of Brittney Sahin awesomeness!

The Costa series carries such heat and passion which is then perfectly blended with humor and crazy scenarios! Loved the sassiness of Callj and gloomy conflicted nature of Alessandro. As is customary, we do have some familiar characters making small cameos in the newest series which is what is one of the reasons there is such a Brittney following- along with her brilliant storylines and writing skills!

Brittney never disappoints. Another great book that you can't put down. Callie and Alessandro are a perfect match. I would give more than 5 stars if I could. Love the Costa's and can't wait for next story and a new book boyfriend.

She has done it again. I cannot explain how much i loved this book. Laughs, smiles and even some tears (happy and sad of course). I took so long to finish it because i didn’t want it to end! I love how she entangled all other characters from different books, she even added baby Remi! I cannot wait for more Costa books and many more series to come!

These Costa boys just get better and better! I loved getting to see playboy Alessandro fall hard and fast for Callie. Like always I was kept on my toes in the best way possible! It was also amazing getting to see Izzy come into her own along with her story being set up! A must read recommendation from us!!

Cupid fells the Casanova Costa. Alessandro is the ultimate billionaire playboy sure in his bachelorhood. After one conversation with Calliope (Callie), he knows he's hooked and that he should walk way. Fate intervenes when a marker is called in and Callie becomes his to protect. A fake marriage is all that stands between Callie and the brutal world of her mafia father. Determined not to break her heart or fall for his wife, Alessandro realizes Callie is everything he wants but will they survive to get their HEA? Their love story has a meet cute, all the feels, plenty of heat plus all the action you expect from this series. The whole Costa clan makes appearances as well as several characters from the Dublin Nights series (reading that series is a plus but not needed for this book). Can't wait for the next book in this series.
