YOU by Caroline Kepnes

YOU is a brilliant novel that illustrates obsession, murder, humor, wit and sex in way that grips the reader as tightly and tenderly as a lover. It's impossible to set it aside, impossible to to forget and the words linger in the mind long after the book is finished.

I suggest highly that you pick up this gem, but do get the Audible version, because the narration is unparralled.
