Thirteen-year-old Abraham "Bram" Stone has never lived an ordinary life. Home is a monastery in the Himalayan Mountains, where the monks train him in otherworldly fighting skills. Bram's father, Elijah Stone, leads a group called the Brimstone Network, an order of warriors and sorcerers who provide the last line of defense against all paranormal dangers.

Bram always knew that one day he'd take his father's place. But that day comes far too soon when a bizarre man named Mr. Stitcharrives at the monastery and breaks the news to Bram: Every member of the Brimstone Network, including Elijah, has been assassinated. Suddenly it's up to Bram to form a new Brimstone Network out of the rubble of the old, in the hope that he can rise to the challenge in time to stop a terrifying threat to humanity.
