The Medford Public Library is co-sponsoring a talk with artist Ricardo Diseño and writer Steve Mockus about their latest book, “Eerie Legends: An Illustrated Exploration of Creepy Creatures, the Paranormal, and Folklore from around the World.” It’s a fascinating and frightening collection of folk tale monsters, ghosts, and other scary things that dwell in the dark.
