It's a batty world in the winter...
Raya is a bat shifter who grew up in the shadow of her perfect sibling, but she's determined to shine in her own moonlight when she becomes a FUCN'A agent. Unfortunately, her first assignment is on a task force run by her sister, and she's paired up with a grumpy—albeit ridiculously sexy—Christmas-hating reindeer.
She'd rather suck on menthol-flavoured gumdrops than take the case, but there's no other choice. She'll have to travel to Christmas Town to thwart would-be immortality chasers with a man who has a candy cane to pick with the big man in red.
The entire future of holiday magic hinges on a reindeer with no Christmas cheer, a vampire bat trying to prove herself, and a town full of secrets...
