Kissing Krampus

When Leda was a child, she was taken to a land of glitter and soft voices and told she was there to stay. In a rush of confusion, a creature appeared and demanded that she and others be handed over. In the blink of an eye, she is back in her bed, but she remembers the creature, she remembers being taken, she remembers everything. The day her nephew went insane, she had her suspicions, and when she ran a test, she knew.
He had gone naughty right before the holidays, and she was the only person who knew why. She had a mission. She had a goal. She had to go talk to a monster known for abducting children.
