The fourth installment in this exciting, humorous chapter book series, in which Lexie Wilde and her undead friends--including a zombie, a skeleton, a werewolf, and a ghost--face off in an ancient challenge that could cost them the entire camp. Lexie Wilde is having a terrifyingly fun time at Camp Croak with her ghoulish pals. That is, until the unpleasantly pleasant scouts from Happy Hollow issue a deadly ancient challenge. If the Ghost Scouts lose, their beloved camp will be destroyed. Lexie and her friends--Bébé, Mary Shelley, Emmy LouLou, Sweet Boo, and Barnaby--must summon all their courage to defeat the wicked Euphemia Vile and her Happy Hollow crew for good. But watch out: the malicious whispering snakes are loose! Could working together be the answer? Taylor Dolan delivers a delightfully action-packed fourth book in the creepy-yet-sweet Ghost Scouts series. Mayhem at Camp Croak! includes her stylized, fantastically funny two-color art.
