The series continues, this time with the gang's plan to go to New York scuppered by a massive snowfall. Their monster friends are terrified of the snow, so Jack and friends decide to introduce them to a post-apocalyptic Christmas. On the Rezzoch front, a new threat rises, a human who speaks the language of Rezzoch and Co, and seems to have some control over zombies. Something bad happens to one of the gang, and things look bleak. Can Jack save the day again?
Still funny, still bonkers, and Jack's desire to risk all to save his friends makes him one of the best pre-teen heroes around.
