Young Jin survives on his own in the streets of Thama, using his wits and climbing skills to find food and shelter. On a bitterly cold night, desperate to avoid freezing, he enters the burned wreckage of a long-abandoned warehouse searching for anything of value. Searching despite the danger—for the warehouse once belonged to jinxers, and no one knows how their magic works...or how long it remains. Jin discovers a beautiful crystal sphere in the ashes—and suddenly finds himself transported to the desert world of Darha.

His foreign appearance immediately brands him an outsider, and he must rely on his Darha friends to conceal him from the mysterious rulers of the local fort. But Jin must face the fort's dangers—for inside may lie the key to his return to Thama...and the key to his own hidden magic powers.
