The infamous, Most Wanted Goosebumps characters are out on the loose and after you. For the first time ever, it's a Goosebumps Christmas!
Kate Welles doesn't want to be special. She just wants to play the lead in her school's Christmas play. Her annoying "friend" Courtney is constantly getting in the way of that. Can you even call someone a "friend" if all they do is make fun of you and ruin everything all of the time? But Kate has to get along with Courtney or else neither of them will be allowed to take part in The 12 Screams of Christmas.
Kate and Courtney's teacher decides they need to find a special place to rehearse. A certain house with a special history. The kind of place that Kate would normally be pretty frightened to go into. The kind of place that gives new meaning to the term: Christmas Spirit.
