You By Caroline Kepnes. From debut author Caroline Kepnes comes You, one of Suspense Magazine’s Best Books of 2014, and a brilliant and terrifying novel for the social media age. Welcome to the mind of Joe, a seemingly normal guy that works in a bookshop. However, there is nothing normal about Joe. His mind is a fascinating place to be, turning brief encounters into meaningful events and even, obsessions. He's a stalker, a murderer and the most candidly honest character that I've ever crossed.
