The 320-page middle-grade novel follows a bullied child and a shadowy creature; hardcover, ebook and audio editions share a September 29 date.

Tony DiTerlizzi's illustrated middle-grade novel The Wump is due September 29 in hardcover, ebook and audiobook formats. Penguin Random House's listing gives that date for all three and identifies Dial Books as the hardcover publisher. The hardcover is 320 pages, ISBN 9798217004911 , and the audiobook listing runs 5

hours 29 minutes. Timothy tries to avoid hurting anyone, even the insects he loves. When a shadowy creature starts feeding on his darkest thoughts, bullying at home and school turns into a dangerous desire for revenge. The publisher describes two-colour illustrations throughout, with DiTerlizzi credited as both writer

and illustrator. The publisher lists the book for ages 9–12. That makes the supernatural premise a middle-grade read with a darker edge; readers can check the official format listing for local availability and a sample before choosing an edition.
