Nightmares! the Sleepwalker Tonic

"Coraline meets Monsters, Inc. in this delightfully entertaining offering from actor [Jason] Segel and co-author [Kirsten] Miller." -Publishers Weekly, on book one in the series
Stay up late with the hilariously frightening middle-grade novel Nightmares! The Sleepwalker Tonic. If you snooze, you lose!
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.
