While exploring a cave in New Mexico, 16-year-old Nathan stumbles upon someone unexpected—the Explorer’s League Science Officer Satou. Equally surprised when Nathan breaks through the security barrier, Satou does the only thing he can and abducts the human interloper, and forever changes the balance of the universe.
Nathan is introduced to the Consortium, an intergalactic league of explorers, scientists, soldiers, and diplomats. He discovers the Universal Map, an ancient artifact locked away long ago by someone simply called The Cartographer. After accidentally unlocking it, Nathan unknowingly begins a chain of events that threatens to tear at the very fabric of the universe. With the assistance of The Explorer’s League, can Nathan stop the war before it reaches Earth and destroys everything he holds dear?
