Just when thirteen-year-old Bram Stone has gotten the hang of running the new Brimstone Network, an unexpected shock is sent his way. Ligeia, queen of the specter -- the mother he's never known -- suddenly appears in his life, leading Bram to explore his specter half as he never has before.

The reunion is overshadowed by a dark threat from Barnabas, an evil specter warlord. In this final showdown between the Brimstone Network and Barnabas, Bram and his team must join forces with the unlikeliest of allies to wage a war against their foe and his secret weapon: the mysterious being known as Trinity.
