Lisa Deresti Betik used to spin wild tales about invisible, blanket-eating alligators in her room, and now she writes fun, fascinating nonfiction books for children, including In the Dark: The Science of What Happens at Night. Born in Sault Ste. Marie, Ontario, Lisa grew up surrounded by majestic lakes and forests that encouraged her curiosity. She now lives in Waterloo, Ontario, with her family, where she keeps a Little Free Library on their front lawn.
