The first book in a hilarious chapter book series about an accidental rule breaker from Katherine Applegate, Newbery Medal–winning and bestselling author of The One and Only Ivan, Endling, and Wishtree.

When his classmates can't sit still for a big performance at school, Roscoe Riley takes matters into his own hands with a liberal dose of Super-Mega-Gonzo Glue—which his mom calls the don't-you-dare glue because Roscoe isn't supposed to use it.

Roscoe doesn't mean to break the rules—he just can't help himself! After all, his teacher's job might be at stake and desperate times call for desperate measures.

Roscoe and his comical misadventures will appeal to fans of Megan McDonald's Stink series; Nancy Krulik's George Brown, Class Clown series; Rebecca Elliott's Owl Diaries series; and Dan Gutman's My Weirder School series.
