From Goodreads ~ If he can’t have her ...
Dr. Sheila Tao is a professor of psychology. An expert in human behavior. And when she began an affair with sexy, charming graduate student Ethan Wolfe, she knew she was playing with fire. Consumed by lust when they were together, riddled with guilt when they weren’t, she knows the three-month fling with her teaching assistant has to end. After all, she’s finally engaged to a kind and loving investment banker who adores her and she’s taking control of her life. But when she attempts to end the affair, Ethan Wolfe won’t let her walk away.
... no one else can.
Ethan has plans for Sheila, plans that involve posting a sex video that would surely get her fired and destroy her prestigious career. Plans to make her pay for rejecting him. And as she attempts to counter his every threatening move without her colleagues or her fiancé discovering her most intimate secrets, a shattering crime rocks Puget Sound State University: a female student, a star athlete, is found stabbed to death. Someone is raising the stakes of violence, sex, and blackmail ... and before she knows it, Sheila is caught in a terrifying cat-and-mouse game with the lover she couldn’t resist - who is now the monster who won’t let her go.
Sheila is a professor, who while dating a banker named Morris, has an affair with Ethan, her much younger teaching assistant. When Morris proposes, Sheila breaks it off with Ethan but Ethan isn't going to make it easy for her. He threatens to publish a video of them and tell everyone about their affair. Eventually Sheila realizes she has to be honest with Morris about it and hopes he'll understand and still want to marry her. When Ethan discovers she's done this, he decides that if he can't have her no one can and arranges for Sheila to disappear. Morris can't believe she would leave like that and suspects something has happened to her and doesn't give up looking for her.
I've liked other books by this author and thought this one was okay. It is written in third person perspective with a focus on where the action was. I thought some of the actions were extreme and unbelievable but went with it ... like how Ethan got away with what he did and that Morris could perhaps forgive Sheila after all that had happened. There were a lot of addictions, which was excessive ... I thought picking one would have been enough for the story. As a head's up, there is swearing and violence.
