Nancy Drew meets Harriet the Spy in this action-packed and heartfelt debut middle grade following an overzealous amateur sleuth as she investigates a shocking family secret-and unravels the mystery of her developing feelings for girls.

Rule One: Your loyalty is to the case.

Amateur detective Pepper Blouse has always held true to this rule, even if it meant pushing people away. But when the results of Pepper’s latest case cost her any hope of the girl she likes returning her feelings, she decides that maybe she should lay low for a while.

That is, until her Great Aunt Florence passes away under mysterious circumstances. And even though her dad insists there’s nothing to investigate, Pepper can’t just ignore rule fourteen: Trust your gut.

But there’s nothing in the rulebook that could’ve prepared her for the family secrets her investigation uncovers.

Maybe it’s time to stop playing by the rules.
