THE BRAND NEW York Times and USA Today bestselling series

Humanity has finally found a fresh home, but the price is blood …

After an extended, perilous journey, Hell Divers Xavier Rodriguez and Magnolia Katib discover the Metal Islands, a sunny habitable zone where thousands of people live by fishing and farming. But this “paradise” is often a violent warrior culture ruled by the cannibal king el Pulpo. For the first time in X’s life, he is forced to lay out his arms and surrender.

Back on the airships, the Hell Divers are recovering from a gruesome finding in Red Sphere, where they learned the truth about World Battle III. Now they need to combat another war-this time for what remains of their very own endangered species. As the fight techniques, alliances will end up being forged, as well as others broken.

Forced to combat in the Cazador army, X encounters his toughest mission yet. Can he help his people drop from your sky and state the promised property, or will mankind go extinct?
