Antimony Carver is a precocious and preternaturally self-possessed young girl starting her first year of school at gloomy Gunnerkrigg Court, a very British boarding school that has robots running around along side body-snatching demons, forest gods, and the odd mythical creature.

Antimony Carver and friend Kat begin their second year at Gunnerkrigg Court. They find a tomb of ancient robots which leads the two friends to question how they are linked to the mysterious ghost that attacked Annie the year before.
