Nine years ago, Skytown soldiers brutally murdered Kenton's family. Now those same men aim to return and destroy Kenton's hard-won, idyllic life amongst the peaceful shifter people of the Hinnom Forest.

Meanwhile, Laine Riven-dragged from Earth to Thorunn against his will-is stuck navigating an unfamiliar school, his jerk of an uncle, and the rising threat posed by the Outpost Terrorist.

When their paths clash amidst tragedy and betrayal, Kenton realises he and his best friend Bo may have rushed headlong into a situation too impossible to fix.

Time is running out as frix season closes in, and their only shot at victory hinges on outrunning the seasoned bounty hunters, savage creatures, and unpredictably violent weather trying to kill them every step of the way. . .
