What a great read! Alessandro and Calliope's chemistry is off the charts! Brittney you have done it again.
I don't know how you keep getting better and better with your books, but wow you did with this one!
I love seeing some of the other characters from your books join the Costas. You brought some of my favorites to this one. Sebastian😍🥰 Emilia🤩!
This book has action, angst, heartbreak, and love. All the emotions packed into one book.

I LOVED this book! From the finest chapter to the last, I could not put it down. Billionaire Alessandro, whose “side gig” brings him into Calliope’s life is a hero who will never settle down. But to save Calli, he needs to fake marry her. Calli is her own force to be reconned with and gives Alessandro a run for his money. This book has action, suspense, humor and tears. Great book to read if you love romantic suspense. Brittney Sahin writes the best books and series and this book is no different. Not Mine To Keep will keep you hooked til the end. I highly Not Mine To Keep and all of Brittney’s books. Enjoy ☺️

We step back into the Costa family series with this one. I have to admit that Alessandro intrigued me in the previous book so I was excited to get to know more about him.

Alessandro finds himself temporarily married to Calliope in order to keep her safe. He’s constantly reminding himself she’s not his to keep. Everyone has different sides you only show to certain people….this was definitely true for Alessandro.

Callie is suddenly married to a man she barely knew but deep down she wasn’t afraid. She wants nothing to do with her father’s legacy. Alessandro seems to be the best solution to finally breaking free. If only he was hers to keep forever.

Alessandro and Callie’s chemistry was off the charts, even when they fought hard against it. There was a natural progression to their relationship. In true Brittney fashion, there were some twists and turns along the way. I really didn’t know how this book was going to end and I loved that! The story itself was amazing and I didn’t want it to end. I cannot wait for Hudson and Izzy’s book!

Not Mine To Keep is a wonderfully written story of two seemingly different characters, Playboy Billionaire Alessandro Costa and School Teacher/Singer Calliope Dawn Anderson or as her Maffioso Father likes to call her, Calliope DiMaggio, Maffia Princess.. The reader quickly learns of the path these two are forced to follow as we watch how they protect their hearts despite the sizzling chemistry brewing between them. In true Brittney fashion, the author wove a riveting story filled with the angst, passion and chemistry her characters are known for. Their were lots of twists and turns in the storyline before Alessandro and Callie finally got their HEA.
I loved Callie's sassy spirit and Allesandro's unwavering loyalty.
This book had all the feels for me! A bonus was how Brittney seamlessly sprinkles tidbits of characters' past; which adds a touch of realism to the story. besides, who doesn’t love a quick catch up of some of your favorite characters. .

Well done Brittney Sahin, another incredible book!

This series is fantastic so far. It's the kind of book you don't want to put down but at the same time you want to savor the story, so it doesn't end to soon. I can't wait for more to come. Looking forward to the possibility of Izzy and Hudson...

This is the second book in the Costa Family series however it can be read as a standalone and you won't be lost, however I highly recommend reading Let Me Love you.( you won't be disappointed) Alessandro and Calliope's chemistry is evident from the time they meet. This story is a perfect slow burn with some twists and turns you don't expect. Alessandro is the perfect book boyfriend that will do anything to protect Calliope even when he doesn't think she is his to keep. As always Brittney captures your attention and you can't put this one down, another 5 star read and I can't wait for the other books in series

The Costa Family Series is fabulous and Alessandro’s Story is no different. His past keeps him locked down of any feelings. A debt brings him into Callies life. Fighting their attraction and feelings the story unfolds and lines blurs. The enemy comes closer and the question remains who can you trust.
Amazing read and I can’t wait for the next Costa Book.

NOT MINE TO KEEP 🌟🌟🌟🌟🌟

**I received an ARC copy of this book in return for an honest, unbiased review. All thoughts are my own**

NOT MINE TO KEEP is the second book in Brittney Sahin’s Costa Family Series ( Let Me Love You being the first).

Summoned to a meeting, acclaimed Billionaire Alessandro Costa meets Calliope DiMaggio, reluctant mafia heiress whilst waiting for his acquaintance to arrive. Despite there being an undeniable attraction Alessandro has neither the time or inclination for a long term relationship and when he discovers that ethereal beauty Calliope is in fact his next ‘job’, he vows to keep her safe whilst keeping his distance.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-


Alessandro is a damaged, antihero who keeps his soft side hidden under a hard exterior. Calliope is an independent, stubborn woman, who cares deeply about those around her.

Ms Sahin writes her characters so beautifully you can’t help but empathise with them. She writes charismatic heroes with flaws, true heart and believable emotions and well rounded, interesting side characters. Whilst you are completely focused on the main characters, Sahin somehow manages to weave sub plots in there that hint towards possible future books.

The villains in NOT MINE TO KEEP really are shiver inspiring - Ms Sahin doesn’t need to go into heavy, dark descriptions to paint a picture, instead she cleverly gives the reader just enough information to come to their own conclusions.

Ms Sahin’s ability to not only come up with dark, intricate and complex plots, but to write in such a way that the reader can painlessly follow along is enviable. I am in awe at her ability to keep all her ducks in a row. No subplot is left hanging and each thread is neatly tied in a bow by the end.

I absolutely loved this book! I admit that I was unsure whether I would ‘feel’ Alessandro before starting. The whole ‘Mafia’ thing normally isn’t my thing, but it isn’t overdone in the book and I really did enjoy it. I also like the length of this book - At no point do you feel like there’s a rush to get to a certain point in the story. I find some authors writing a bit ‘formulaic’, something that Ms Sahin’s books most definitely are NOT. She lets the story run its course and come to it’s own conclusion when it’s ready and the book is all the more enjoyable for it. There were also several cameo appearances of characters from Ms Sahin’s previous series, something (being a fan of Ms Sahin’s previous work) I really enjoyed. That said I don’t think it detracts from the story for those who are new to Ms Sahin’s work. NOT MINE TO KEEP is the second book in the Costa Family series and whilst it is a stand-alone I would highly recommend you also read ‘Let Me Love You’ the first in the series.

NOT MINE TO KEEP is a story including:
Repressed attraction
Mafia
Suspense
Age gap (10 years)
Forced proximity
Vile villains
Flawed hero
Family angst
Plenty of action
A soupçon of humour
And of course a HEA.

I really enjoyed this book. This is the second book in the Costa series. Alessandro and Callie are great main characters with outstanding chemistry. They get to know each other as the story progresses. They also learn to trust each other. Alessandro is very protective of Callie. He really wants to take care of her. Callie does not back down to Alessandro. She gives as good as she gets. The twists and turns of the story were done well. I loved seeing characters from the other books. The Costa family is wonderful. Overall, this is a great book and a great addition to the series. Brittney keeps getting better and better with each book.

Another must read book written by Brittney Sahin. This is the second installment of the Costa Family, and it revolves around Alessandro and Cassie. Some other characters from her prior books make an appearance which is something I love about her books, but don’t worry, you don’t need to have read her prior books to follow along. As always, Brittney takes us on a journey of adventure and romance with twists and turns that keeps your interest until the end. Alessandro and Cassie’s chemistry is off the charts and throughout the book, during different circumstances, you can truly feel people’s emotions and what they are going through.
If there is something I would have changed, would have been having more intimate scenes between Alessandro and Cassie sooner in the story, but this wouldn’t change my rating
I can’t wait until the next Costa Family journey and see where Hudson and Constantine take us.

Such a great read that I couldn’t put it down…….again. Each book she writes is amazing on its own with the plot, character development and balance of action, humor and passion. Then she is able to subtly tie in other past characters seamlessly that it creates a world I forget is not actually real. Great job again Brittany! Can’ not wait for Hudson and Izzy next.

Once again Brittney has delivered a book that is hard to set down. Great characters that are well developed and have you falling in love again. Alessandro was a great character and had great chemistry with Calliope who was also a fantastic character. Lots of suspense and action and great secondary characters kept the pages turning until the end.. Loved the story line and the characters and the little twists along the way. This author never disappoints her fans so make sure you clear the time to read as you won't want to stop reading. Loved it!! I am volantarily reviewing an arc I received. Loved it!

Wow! Just, wow. I honestly wasn’t sure what to think of the two of them from the first chapter or so… but I found Calliope really easy to relate to and found myself really worrying about Alessandro. Next thing I know, I’m dreaming about the book and staying up late to finish it- and that ending (so perfect!)

This book will capture you from the beginning. The chemistry between Alessandro and Calliope is sizzling hot. I absolutely loved the storyline for this book. Nothing like lust, Mafia, arranged marriage, war and finally love. This book will pull you in and not let you go. You will love the Costa family and their loyalty to family, friends and protecting the innocent.

"Not Mine to Keep" has been my favorite book in this series so far! Callie and Alessandro are perfection.

And can someone PLEASE do the character art for Alessandro in a cowboy hat. I need to see that!!!

A job.
A big job until its not.
Alessandro is everything any country girl would want except a future, one and done is his motto, until a favor is called in.
Calliope is nothing like any woman that Alessandro has ever been around, although even before she becomes the target he is drawn to her for some reason and we are off and running.
Lots of twists and turns in the storyline as well as deep feelings on both sides especially on Calliope's part until she breaks down Alessandro's wall but once they fall, it may be too late.
X squared, Loved it.
This Costa Family is so exciting, they just keep getting better and better.

Brilliantly Crafted, “Not Mine to Keep” masterfully flows with the relationship between Calliope and Alessandro. This intense romance that continues the Costa Serie wonderfully captures the shift from initial mistrust to steamy love with unexpected authenticity. Unlike many in its genre, the book avoids clichés, offering an engaging and believable storyline. Sahin's knack for character development shines as a testament to her ever-evolving skill as a storyteller. This book completely had my attention from chapter 1, and I literally could not put it down. I read the whole thing in nearly one sitting.

This book is incredible. So well written. Love the side characters as always. Alessandro and Calliope are everything. The spark from their first meeting. The tension in their back n forth. The spice of them finally getting together. The suspense and drama. Just incredible. This series has it all but this is my favorite book thus far. Maybe one of my all time favorites ever! The vulnerability that he shows. The strength she shows. Individually they are strong but together they are unstoppable. He's on a mission to save her but she ends up saving him. Did I mention this book 📖 s incredible. Unputdownable for sure!

"Not Mine to Keep" is the second installment in the Costa Family series by Brittney Sahin. Sahin's storytelling immerses readers into a captivating fictional world. I was engrossed in the book and couldn't set it down!!Alessandro and Calliope's chemistry was evident from the start, with a slow-burning intensity that I found delightful. Both characters must learn to trust each other to thwart her father's plans. The story unfolds with twists, action, and a gradual buildup of emotions. I always enjoy the appearances of characters from other series, but don't worry if you haven't read them yet! I'm eagerly anticipating the next book in the Costa Series.

I got a chance to receive an ARC of Not Mine To Keep and I am in awe how each book gets better when I think the last one by Brittney cannot be topped. The story between Alessandro and Calliope is a rollercoaster of the best emotions. You know a book is good when you forget to breathe when reading because you’re so drawn in. Alessandro is the bad boy that every girl wants to receive love from and Calliope was just the strong woman to turn his world upside down. I cannot wait to see the continuation of these stories!
