Tom is a successful author, but he's struggling to finish his novel. His main distraction is an online admirer, Evie, who simply won't leave him alone. Evie is smart, well read, and unstable. She lives with her father, and her social-media friendships are not only her escape–they're everything she has. When she's hit with a restraining order, her world is turned upside down, and Tom is free to live his life again, to concentrate on writing. But things aren't really adding up. Tom is distracted by and addicted to his online relationships, and when they take a darker, more menacing turn, he feels powerless to change things...because maybe he needs Evie more than he's letting on.
