Subtitle from cover.

"For the first time ever, Christmastown is celebrating a strange new tradition--Halloween. But not everyone is willing to watch their dependable winter wonderland get overrun by carved pumpkins and costume parties. As a series of scary happenings hits Santaland, each one more intense than the last, April realizes having a role in the festivities could cost her family, friends--even her own life. April isn't the only unlucky target. Outspoken elf Tiny Sparkletoe is found dead in the snow outside his cottage, crushed in the middle of what appears to be a monstrous footprint. With mayhem descending like reindeer on rooftops, April must stop the Halloween killer before the fate of Mrs. Claus becomes another creepy tale to tell in the dark . . ."--Back cover.
