Madame X by Jasinda Wilder

Dark and sad story spiked with great sex scenes!

She is strong, arrogant and unattainable for her students... But in her private life she is trapped, even though she is not aware of the level of confinement because its all she have ever known, and she is scared of disrupting her carefully planned schedule.

She doesn't know who she is, what she likes, or what happened to her that night.

Caleb is dark and mysterious but not in a good sexy way, even though she describes him as beautiful and good looking, in my mind he is a horrible person. 
He is restricting her and not in a fun way, I'm almost certain he had something to do with what happened to her, that is the level of darkness I sense from the character.

And then its Logan, he has darkness and a bumpy past, but he sees her, really sees her, and finds himself in her darkness.

I couldn't believe she left again, I know it was scary, but dude the guy has random fucks in his whole building and still you feel like home there, wtf?

HUGE cliffhanger at the end, I need the next book like yesterday!
