Swan Lake by LB Alexander 

Doubts and fears of her own making have kept April a prisoner of her mind for far too long. Her promising ballet career was halted after a violent attack, forcing her into a rehabilitation facility to cope with her crushing emotional pain. Now, eager for a fresh start, she battles to hide her daily struggles under an ill-fitting mask of control.

Until she meets William. Underneath his intoxicating guidance, April explores exquisite freedoms that unlock a powerful side of herself she never knew existed. But the handsome billionaire has a dark side of his own, and may not be the modern-day prince the world believes him to be. Plagued by labels of both good and evil, will he be her salvation? Or her ultimate undoing?
