With summer approaching, Ellie Avery’s schedule is ruled by attending end-of-the-year events at her kids’ school—and avoiding run-ins with her arch competitor. When a murder disrupts the core curriculum, can the two women form an alliance to teach the killer a lesson in justice?

As a regular volunteer at North Dawkins Elementary, Ellie would never miss the annual Mother's Day breakfast—even if she has to tolerate the likes of Gabrielle Matheson. The rivals aren't exactly sworn enemies, although Ellie still thinks there's only room for one professional organizer in their small Georgia town.

But when Ellie sees Gabrielle in the hallway, she’s a mess. It looks like Gabrielle’s seen a ghost—or, as she explains, a dead body inside the supply closet. Before Ellie can get help the body vanishes . . . only to mysteriously reappear later at the school.

Little is known about the victim, a secretive snoop with a nosy nature and a penchant for keeping quiet about her own past. Ellie will leave no desk unturned to protect her kids and expose the cunning criminal’s identity. Because if she doesn’t, the killer may chalk up another textbook case of murder . . .
