From the bestselling author that brought you the award-winning Extinction Cycle series comes an all new vision of the apocalypse and the future of humanity.

Ten years ago, Hell Diver Xavier “X” Rodriguez fell to Earth. Those he left behind went on without him aboard the airship he once called home.

Michael Everhart—the boy once known as Tin—has grown into a man and the commander of Hell Diver Raptor Team. While Michael dives to help keep the Hive in the air, Captain Leon Jordan rules with an iron fist at the helm of the ship. But unrest stirs under his strict leadership as a prophecy of hope sweeps the lower decks.

When a mysterious distress signal calls the Hell Divers to the surface, Michael and his loyal team begin to uncover long-buried truths and the secrets Captain Jordan will do anything to keep. They dive so humanity survives … but will they survive the ultimate betrayal?
