Bobby is still uncertain about what happened to his family after he was recruited as a "Traveler," a heroic role that first pitted him against the shapechanging monster, Saint Dane, in the series' debut, The Merchant of Death. It's a radically different life from that of junior high student in Stony Brook, Conn., where his friends Mark and Courtney eagerly await the journals in which he updates them with the latest events from various colorful "Territories." In the fabled city of Faar, beneath the waves, Bobby meets Spader, who is also a Traveler, and quickly becomes his first mate. Unbeknownst to Spader, his submerged city is partially responsible for the peace felt above the surface in the floating habitats. When Saint Dane decides to annihilate Faar, Bobby and his Traveler buddies must race to outwit the villain. Things aren't exactly calm back on Second Earth. The town bully has discovered one of the pages and is threatening to expose Bobby's secret mission to the police (who have no idea why Bobby and his family have disappeared) if Mark and Courtney don't share the journals with him.
