by Calyane Fae

Sophia Brennan has nowhere to go. She fled to Berlin to study psychology with nothing but a suitcase, refusing to crawl back and become what terrified her like her mother, controlled and dependent. When a notorious playboy offers her a live-in assistant position, Sophia takes the job knowing his previous assistants all made one fatal mistake: they fell in love.

André Patberg has never been himself. He's performed his whole life as his parents' business deal and for everyone who wants something, convinced love is just another transaction in a world where nothing is real. When he hires an assistant who wants the job instead of him and sees past every performance, André risks what he's never risked: his heart. But falling for Sophia forces André to admit love might be real, shattering everything he's believed about himself and the world.

Sophia realizes falling for André means becoming everything she swore she wouldn' another assistant who believed she was special, another woman dependent on a man who holds all the power. To win his independence, André must accept his parents' conditions: the right match, the strategic choice, and losing the woman who taught him what real means.

I really liked the banter and how the story developed. I like how both Sophia and André broke away from family expectations and redefined their lives on their own terms.

I'm only a few chapters into The Player Theory, but I already have a strong feeling this is going to exceed my expectations. This is the second book I've picked up by Calyane Fae, and once again I'm completely mesmerized by the writing. There's something about the way the characters are introduced and how their emotional layers begin to unfold that immediately pulls me in.

Sophia and André already have such an intriguing dynamic, and I'm excited to see how their journey develops. The blend of emotional depth, witty tension, and believable chemistry makes it hard to put the book down.

If the rest of the story is anything like this opening, I know I'm in for an unforgettable read. Calyane Fae has quickly become an author I'll happily keep coming back to, and I can't wait to see where this story takes me.

Review...
I saw this book on booktok and I added it to my tbr. This is a good story, opposites-attract, college setting, boss/Assistant, he falls first, then add this to your TBR. I liked Andre and Sophia they are cute together but unfortunately being together isn't easy due to his family. definitely worth a read 📚 👌

Loved it

I enjoyed this, loved the characters. He made mistakes but had his real friends to bring him back down.

Sometimes you have to find your own family when yours is crap.
