At their twenty-fifth high school reunion in Portland, Maine, P.I. partners and moms Maya Kendrick and Sandra Wallage must figure out which of their former classmates should have been voted most likely to kill . . .

After all these years, Maya and Sandra have mixed feelings about seeing their high school classmates, but in one sense the evening promises to be something of a red carpet event. A shy wallflower in school, Alyssa Turner has blossomed into an Oscar-nominated actress-and she's coming to the reunion.

To their surprise, before the event, Alyssa contacts Maya and Sandra. She's going to be playing a private eye and would like to hear about their experiences. When they meet, she confides she was bullied in school by cheerleader Tawny Bryce and her mean girls' clique while also having a huge crush on Tawny's boyfriend, the star quarterback.

When Tawny's body is discovered the night of the reunion behind the bleachers, the spotlight is on Alyssa. She turns to Maya and Sandra to find the real killer. But is she as innocent as she seems-or turning in another Oscar-worthy performance?
