Some secrets are like Christmas lights: they get worse the more you try to untangle them.

Noelle Cooper is teaming up with her family to launch a festive new venture: a holiday extravaganza complete with Santa, gallons of eggnog, and a spectacular tree lighting guaranteed to make the season merry and bright.

There's just one problem: Holly Winterbourne, the abrasive holiday consultant Noelle's father has hired to help pull it off. Holly insists on holding a practice run at Babbling Brook Campground?in the middle of July?and she rubs everyone the wrong way.

When an incident at the tree lighting turns deadly, the festivities come to a shocking halt. Noelle feels partly responsible for the tragedy, but then the police determine that it was no accident, and Noelle's guilt turns to suspicion. She sets out to discover who tried to pull the plug on the festival.

As Noelle and Mandy secretly sift through the evidence, they learn that several people at the event were up to no good. But which one actually did the deed? It might take a Christmas miracle to find out.

Can Noelle unravel the clues and expose the killer before Christmas in July loses its sparkle?
