Mormons are totally fascinating. To wit: the success of Jon Krakauer's true-crime book Under the Banner of Heaven and Mitt Romney's entire political career. Tonight, Ebershoff reads from his newest novel, a sweeping epic called The 19th Wife. Ebershoff will hold forth on his years of research into topics like how fucked up Brigham Young really was and what the deal is with those magical Mormon underpants.
