Returning to her role as an amateur detective is the last thing library director Amy Muir wants. She's already buried under an avalanche of responsibilities, including sharing the directorship of the local public library, parenting her holiday-obsessed five-year-old twins, and helping her choreographer husband, Richard, present The Nutcracker as part of the town's festivities. With her frosty mother-in-law, Fiona, visiting for the holidays, Amy definitely has enough on her Christmas cookie plate.

But when the chair of the festival committee is found as dead as Dickens's proverbial doornail at the town's ice rink, Amy is determined to uncover the real perpetrator to protect her brother-in-law, Ethan Payne, who was placed at the scene. The clock is ticking down as Sheriff Brad Tucker is equally sure that Ethan is guilty.

It's beginning to look a lot like the murderer hasn't wrapped up his killing spree, and now, it might just be "lights out" on the holiday festivities--and on Amy's life.
