Twisted Hate by Ana Huang (Twisted #3)

Gorgeous, cocky, and fast on his way to becoming a hotshot doctor, Josh Chen has never met a woman he couldn’t charm—except for Jules f**king Ambrose. The beautiful redhead has been a thorn in his side since they met, but she also consumes his thoughts in a way no woman ever has. When their animosity explodes into one unforgettable night, he proposes a solution that’ll get her out of his system once and for all: an enemies with benefits arrangement with simple rules. No jealousy. No strings attached. And absolutely no falling in love. Outgoing and ambitious, Jules Ambrose is a former party girl who’s focused on one thing: passing the attorney’s bar exam.
