Perfect for fans of Joanne Fluke and Laura Childs, when twin sisters Hanna and Alex help out at the local high school reunion, volunteering takes a turn when they find a former classmate's dead body.

Hanna and Alex, owners of the Murder and Mayhem book and chocolate shop, are busy preparing for the Harriston High School’s reunion weekend. Neighbors will connect with old friends and perhaps try to avoid old foes. One person no one can avoid is Kyle, the former star quarterback, who is busy using his entire playbook to try and score with Hanna, even threatening her if she doesn’t play nice. At the reunion, Alex glimpses more drama than nostalgia as insults are flung around like a football at a Friday night game. The party is put on hold when Alex finds the dead body of none other than Kyle himself, bludgeoned to death by a nutcracker that the sisters admired earlier in the night.

Hanna quickly becomes the prime suspect—someone saw her slap Kyle in the face at the reunion dance. She’ll need her sister, their sleuthing canine, Watson, and their old friends and colleagues to help break this case wide open. While looking through old yearbooks and taking a stroll down memory lane, Alex uncovers a few secrets about Kyle, now, it seems like everyone had a motive to kill him.

But when the suspects start becoming the victims, Alex and Hanna know that they can’t melt under the pressure—they must find the killer before they become just another yearbook memory.
