Sometimes, you just want to feel bad, and at times like that there are books like Lost Girls: An Unsolved American Murder. It's a heart-chilling non-fiction tour-de-force about a Long Island killer who's still yet to be caught. Kolker's terrifying and intensely reported book isn't just about a true life murderer, though—the "lost girls" in question are Internet prostitutes who use websites like Craigslist to attract clients, one of whom is the still-at-large killer. Lost Girls exposes an online community and phenomenon that's so far gone largely unpublicized. —Matt Barone
