The final field trip of the school year had gone very well for Xavier Valsaint. He killed it at the science center, impressing his teacher but drawing the unwanted attention of Kyle Reed, the class bully. It should have been the perfect end to Xavier’s middle school years. When the school bus breaks down in the middle of nowhere and with no cell service, Mr. Bisaillon asks for volunteers to accompany him to a house a few miles behind. Xavier and some of his friends volunteer to accompany their teacher. Kyle Reed does, as well, much to Xavier’s annoyance.

The house turns out to be a mansion, the largest Xavier has ever seen. The front door is unlocked and Kyle forces his classmates inside. The house seals itself shut, trapping the students inside and Mr. Bisaillon outside. Soldiers wearing Civil War uniforms surround the house and take the teacher prisoner. The house itself transforms around the students, its opulent features and furniture becoming decayed and rotted.

Something stirs in the basement. An ancient evil has awoken and the students from James Buchanan Middle School are its prey. To survive, Xavier and his friends must stay ahead of a hulking warrior and find a way to destroy the source of the evil within the house…an ancient Native American legend known only as the Raven Queen.
