Nightmares! The Sleepwalker Tonic is the sequel to the hilariously scary New York Times bestselling novel Nightmares! by multitalented actor Jason Segel and bestselling author Kirsten Miller. You thought the nightmares were over? You better keep the lights on! 

Charlie Laird has a dream life. 

1. He has a weirdo stepmom who runs an herbarium. 
2. He lives in a purple mansion with a portal to the Netherworld. 
3. Since they escaped from the Netherworld, he and his best friends have been sleeping like babies. 

But 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. Now her loyal following is heading to Orville Falls for their herbal potions. Weirder, though, Orville Falls is suddenly filled with...zombies? At least, they sure look like the walking dead. Rumor has it that no one's sleeping in Orville Falls. And Charlie knows what that means. 

Things are getting freaky again.
