Combining fact, fiction, and hands-on activities, Frightlopedia is an illustrated A-Z collection of some of the world’s most frightening places, scariest stories, and gruesomest creatures, both real and imagined.

Discover Borneo’s Gomantong Cave, where literally millions of bats, cockroaches, spiders, and rats coexist—in pitch darkness. Learn about mythical creatures like the Mongolian Death Worm—and scarily real ones like killer bees, which were accidentally created by scientists in the 1950s. Visit New Orleans’s Beauregard-Keyes house, where Civil War soldiers are said to still clash in the front hall. Plus ghost stories from around the world, a cross-cultural study of vampires, and how to transform into a zombie with makeup. Each entry includes a “Fright Meter” measurement from 1 to 3, because while being scared is fun, everyone has their limit.
