The Sorcerer Gisborne has claimed his throne. The safe house of Lake Cloudia is in danger as the Golden Arrow, the only remaining source of pure magic, has resurfaced. Nations across the world spring into a frantic search to recover it before the Ealdra can use it to rekindle the power of the long-dormant Gold King and end their feud with the Accyn forever.

Dark secrets surface when Connor Avidor, a strange agent, arrives from the hidden third descendants nation of Narruncen to call Jack to join the search. Meanwhile, the Gold King and Gisborne repeatedly urge Jack away from the Narrunceni. They warn of a powerful warrior of legend, a sorcerer to rival Guy of Gisborne who will sweep in a wave of violence across the world.

Jack is forced to confront his great-grandfather's past while struggling with the weight of loss, the volatile power he is only beginning to control, and the growing uncertainty of who he can trust. In a race across continents, how far will he run?
