Face the uncertain future without fear …

A year has passed since the Hell Divers defeated the machines at Kilimanjaro. The freed captives have settled into their new home at the Vanguard Islands, joining survivors from around the world. But extreme weather and failed crops have raised the specter of famine. Ships must push deeper into dangerous red zones, only to come back with less loot—and fewer soldiers.

When the Hell Divers discover a scroll on a raid, King Xavier is faced with a long-buried truth that threatens the future of his people and all of humanity. The Vanguard Islands are not the salvation the sky people thought them to be. To survive, they must venture through the Panama Canal and into the wastes beyond.

With the future at stake, the Immortal once again dons his armor. But there is a reason the great Cazador armies never returned from the canal, and this time not even the King of the Wastes is prepared for what awaits them.

They dive so humanity survives …

More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers—men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.

When one of the remaining airships is damaged in an electrical storm, a Hell Diver team is deployed to a hostile zone called Hades. But there’s something down there far worse than the mutated creatures discovered on dives in the past—something that threatens the fragile future of humanity.

Back at the Vanguard Islands, King Xavier Rodriguez has been severely injured in another battle to protect the kingdom. Now an infection threatens to kill the one man who can keep the peace. As he fights for survival, new intel from Rio de Janeiro gives humanity hope of destroying the biggest threat of all: the machines—if the machines don’t find the Vanguard Islands first.
