Book 1 in the Bloodline of Yule Trilogy

Charity Jones is a 16-year-old engineering genius who's bullied for being an atheist at her conservative high school. Everything changes when Charity's mother brings home a dreamy teen runaway named Aidan to foster for the holidays. Matched in every way, Charity and Aidan soon fall into dizzying first love.

But it seems Aidan isn't the only newcomer: Charity soon finds the brutally slain corpse of her worst bully, and then gets hard, haunting evidence that something monstrous is stalking Oak County. Can Charity and her Skeptics Club stop the killer?

Christmas is coming...or is it Krampus? Great Christmas horror with a twist for teens and adults!
