The Psychopath Test by Jon Ronson

A zany look at the dark and elusive world of psychopaths -- how to spot them, how we've tried to cure them, and how they've managed to infiltrate some of the most powerful positions in the world. Investigative journalist Jon Ronson adds the perfect amount of his trademark humor to an otherwise horrifying topic. By the end, you'll be giving everyone some serious side-eye. - Kelly
