The holidays are Jenna Hart’s favorite time of year, but just as she’s decorating the Cookbook Nook for all the festive events, her imperious older sister makes a surprise visit, anxious that her husband’s been more naughty than nice. To make matters worse, her father’s good friend Jake shows up on her doorstep with a frantic report that his friend has been murdered—trussed with Christmas lights and impaled with a tree star.

Worried that Jake was the intended victim, Jenna makes a list of suspects and checks it twice. Swapping her Santa’s hat for a sleuthing cap, she gets busy investigating Jake’s long-lost sister, his Grinch of a neighbor, and a stamp collector who covets Jake’s most treasured piece. When Jake himself is poisoned and nearly dies, Jenna knows she’ll have to do whatever it takes to corner the culprit before it’s lights out for Jake . . .
