Books in Igor's Lab of Fear series

Welcome to my Laboratory of Fear! I'm Professor Igor. Yes, THAT Igor. Hehe. Each weird and unsettling specimen in my lab holds a story of science gone terribly, terribly wrong. Lucky for you, I have them locked up safe and sound, away from prying eyes, but maybe just this once I’ll let you have a peak. Don’t be shy, come downstairs to the world's most unusual science lab! And pay no attention to those teenagers working hard on that ancient equipment. Yes, those are chains on their feet, but they're quite happy to be here!
