"There's a lot of horrible things to be afraid of. I want to stop something. I want to save someone. I want to know I did some good, have a use. I want to say to myself, just once: "Bam. Good witch." Gwenna Luna is seventeen and on the run. And she dreams of strange things: A child-eating giant who lives in the woods; ghosts haunting a laboratory; a valley of the undead; a magical book and Jack the Ripper's escape from hell... Why did Gwenna Luna seek out the help of a jaded psychiatrist to unravel these dreams? And is it wise to listen to a girl who just may be... a witch?
