Still recovering from their encounter with Haunting Harry on Halloween, Ember and the crew are in need of a break. Deciding to get away, they head to Scotland to stay in Ember's grandparents' home for the holidays. But when not one, but two uninvited guests appear, it's clear this isn't going to be the relaxing Christmas they were hoping for. Worse, Ember's premonitions are back in the form of horrendous nightmares that have her shaken to the core, and it soon becomes obvious that she and her friends are being hunted by a cult of vampire-hating lunatics. Losing her mind and terrified for Reid's life, Ember knows only one thing for sure: this year, Christmas will be a real nightmare.
