Erik Larson has an uncanny ability to find riveting stories lurking in rarely-explored corners of American history. From the exploits of a monstrous serial killer in Devil in the White City to Guglielmo Marconi's groundbreaking invention of radio in Thunderstruck, Erik Larson proves that a book doesn’t have to be fictional to be wildly entertaining. In our interview, Larson talks about how important reading is for him when approaching his work. "I read promiscuously and voraciously," he reveals. "I have this theory that when you pack your mind full of stuff, your mind comes up with stuff on its own."
