I’m trying to find a book I read ages ago;

Very dark romance, a girl was abducted by some guy, kept in his house as a slave. Trained and everything.

Eventually, he wanted to buy another girl, he finds some guy (a sheik or something?) that sells girls. But they have to go there, so they fly with a private jet.

They are there but he get’s rejected; they slip the girl some message to tell them if she needs help.

Back home, she manages to overpower the guy, puts him in a cage, calls the sheik, prince and goes to live there.

Does anyone know it?

Thanks!!!
