I don't have much to say about this book, i can´t even find the words to write this review.
I loved the main story in here.
The book is all focused on Olivia and Cash's relationship which will show us a huge development in they're actions and the way they view one another. This is the thrive of they're relationship because in a way they don't want another person to mess up the way they have been living but now that the person is the "one" they will struggle with that decision and with being able to fully giving themselves to one another.

"Okay, so I’m a naturally suspicious person, but I have good reason to be.  A lifetime of schemers, liars, selfish buttmunchers and all around icky people has made me a bit jaded.  But I’m coming around.

And with the help of Taryn the suspicious part of Olivia i ranking higher every time...

“Because I know Cash.  That boy has wild blood.  Guys like that don’t change.  And girls can’t make ‘em.  It’s just the way they are. It’s part of why they’re so irresistible, too.  Don’t we all want what we can’t have?”

 The "action" part about the mafia and the Russian's etc... That i tough it was a cool element in here because it had danger and adrenaline to a book that otherwise it would be lovely. We don't want lovely mainly because we want to see what our bad boy Cash can do and  we want to see a bit of Gavin as well....
There are loads of kidnappings, fights and smiling villains.
everything you saw on Down to you you will question here. Marissa and Taryn will be very enigmatic which is kind of weird and it will have strange vibe.
we have mouth opening surprises so get ready for that. A lot of the things you never imagined Will happen, even the impossible ones... I will say no more tough.
The first few pages were a bit hard to read because i couldn't focus on the story but once you get in this vibe you can't let go.  I think that Down to you was more interesting in terms of side story but this one had more on the couple and love parts. Don't get me wrong i went crazy with all this bad boy world but something felt forced or even to fast when i read the book. Like some of the parts were put there just because. But you remove that and M. Leighton gives us and amazing writing full of characters with great personality.
