Traitor: that’s what Tatsu is now. On the run from both Runon and Chayd, Tatsu and Yudai’s only hope for survival is to disappear into the wilds. However, when the siphon’s deadly curse returns, they have no choice but to travel into the desert kingdom of Joesar in search of a cure. Battling the unforgiving elements of the sands, Tatsu starts to realize that the path towards destroying the siphon may claim Yudai’s life. Time is running out as Nota’s fury—and the siphon’s hunger—begin to spiral wildly beyond their control. As their options slowly fall away, the only thing Tatsu and Yudai can count on is each other.
