In the spirit of Halloween and this month's theme of Facing Fears, we asked our friends at Goodreads to tell us their favorite chill-inducing books — that are completely true. They responded with 13 picks that cover everything from unstoppable infectious diseases to disturbing historic murders and journeys gone mercilessly awry. The best part? These spooky stories are all vetted, and highly recommended, by avid readers in the online book-loving community. Take a look to find your next October read.
