All who kill a pterosaur are cursed. But Rob Sardan killed their King.

To break the curse he must escape a prison of ice and crystal, south of south, beyond all hope. With a ragtag team of former pirates, a failed thief, and a strategist who cannot be trusted, they must pull off a heist for a ship that can sail on a sea of fire. They must cross the grinding ice, challenge an empire, and face the dread pirate Skagra before she unleashes the power of the Crown of Black Glass.

Rob has become a hero, but can he live with what it took? Can he face what he has become... King Killer. Sword-breaker. Sky-Slayer.
