Since Charlie and his gang managed to escape unharmed from the Dark World, he has slept like a baby throughout the night. You could say that his life is like a dream: he has a weirdo stepmom who runs an herbarium and he lives in a purple mansion with a portal to the Netherworld. However, Charlie can't shake the feeling that something strange is afoot. Charlotte's herbarium used to be one of the busiest stores in Cypress Creek, but now her loyal customers are heading to Orville Falls for their herbal potions. The weirdest part is that everyone is stumbling around town like mindless zombies. Rumor has it that no one's sleeping in Orville Falls. And Charlie knows what that means. Things are getting freaky again.
