Meet Gwendolyn—once known as Dadah (long story, seriously, there’s a whole other book about it)—the undefeated Jokester-in-Chief of her house! With a talent for pranks and lighthearted mischief, Gwendolyn reigns supreme. But there’s one tiny problem: she’s also the role model for her ambitious little brother, Bevan, who has been watching her very closely. She never considered what being a role model might mean—or what it could inspire.
