Sandy and Sindy wash ashore on a black-sand island that doesn't exist on any map. No powers. No weapons. No escape.

Hunted by hundreds of Ghouls and their leader - Envy, a 500-foot monster - Sandy is about to be erased when Rex Goldfang, the Sin of Greed, walks through the horde with a flaming sword and pistol.

Two Sins collide. One island burns. And Sandy learns the erased history of the Seven Hell Kings, Emperor Vaelor, and a new bounty that shakes the world: Jack the Pride.
