Andrew Shaffer is the New York Times-bestselling author of the essential survival guide, How to Survive a Sharknado and Other Unnatural Disasters, as well as the forthcoming Ghostbusters tie-in, Ghosts from Our Past: Both Literally and Figuratively: The Study of the Paranormal. He's not a scientist. He's more like a game show host. You can find him online at www.andrewshaffer.com.
