Celebration Bay is full of yuletide cheer— but it’s hard to remain festive when someone’s out to slay Santa.  It’s Liv Montgomery’s first Christmas out of Manhattan and in Celebration Bay. They’ve got a tree to rival Rockefeller Center’s, but this year’s holidays are turning out to be a disaster. As the small town’s event planner, Liv wants everything to be perfect. Unfortunately, the local Christmas shop has been replaced by the gaudy Trim a Tree—complete with tacky ornaments and a new replacement Santa who isn’t spreading any cheer.  At the town’s annual Celebration of Lights, Trim a Tree is the only shop left unlit. Liv, furious, goes to investigate, and discovers something even less festive—the store’s new Santa has been murdered. Small-town gossip begins to stir, and Liv must clear the name of the previous town Santa just in the nick of time before the real killer ruins Christmas.
