Keith Winterscar has accomplished the impossible—he's stolen a godsdamned Feather.

After barely surviving the underground temple with his sister and father to repair To'Wrathh's shell, the crew returns to Clan Altosk as heroes. With his father's soul now inhabiting To'Avalis's body, the powers of To'Wrathh herself, and the occult secrets Keith has steadily uncovered—the Winterscars are poised to change everything. But other powers have begun watching the meteoric rise of Clan Altosk.

The grand warlock Hexis has set his eyes on the surface, hungering for power. If the warlock guilds discover that the clan has uncovered the secrets of the occult, the war against the slavers could escalate exponentially into an all-out conflict between all sides.

And To'Avalis will not take the theft of his shell lightly, meticulously plotting every possible move to bring ruin to the Winterscars the moment they step beyond their safe haven on the surface.

As the clan prepares to migrate underground with their newfound arsenal of relic armors, Keith must navigate treacherous clan politics, guard his new family's true nature, and prove to his father he can—and will—survive what is to come.

Because when gods go to war, even the cleverest thief may find himself with nowhere left to hide.
