Bestselling author Chuck Wendig's middle grade debut is equal parts spooky, funny, and heartfelt—perfect for Halloween and year-round reading! A fun adventure about rival siblings running a monster mortuary. *"Playing to strengths demonstrated in his many comics and tales for older audiences, not only is Wendig a dab hand at concocting extremely creepy critters, but here he also pulls together a secondary cast of quarrelsome but supportive allies for the beleaguered teens."—Kirkus Reviews (Starred Review) *"Monstrously fun.... A sure pick for those enamored by Neil Gaiman’s The Graveyard Book (2008), and Tahereh Mafi’s Whichwood (2017)."—Booklist (Starred Review)
