The mission to Rio de Janeiro ended in victory, but it came at a dire cost, killing most of those who set out to rescue the stranded survivors. Even worse, the skinwalkers’ leader, Horn, escaped with his demonic crew and is coming to take the throne. 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. 

After a long, 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 really a violent warrior society ruled by the cannibal King el Pulpo. For the first time in X's life, he is forced to lay down his arms and surrender. 

The Sea Wolf sets out to search for the Metal Islands. Leading the expedition is legendary Hell Diver Xavier Rodriguez. After enduring a decade on the poisoned surface, his survival skills will be put to the test on the dangerous open seas. But storms, sea monsters, and the cannibalistic Cazadores aren't the only threat to X and his small crew. Their mission will uncover hard truths about the history of the war that left humankind stranded in the air for centuries. The fate of those still living on the airships might very well rest on this perilous journey to find a new home.

Left for dead on the nightmarish surface of the planet, Commander Michael Everhart and his team of Hell Divers barely escape with their lives aboard a new airship called Deliverance. After learning that Xavier "X" Rodriguez may still be alive, they mount a rescue mission for the long-lost hero. In the skies, the Hive is falling apart, but Captain Jordan is more determined than ever to keep humanity in their outdated lifeboat. He will do whatever it takes to keep the ship in the air - even murder.

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 Everheart - 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.

A company of Army Rangers is sent on an interstellar colony ship to secure a foothold on a dangerous, alien planet through violence of action. Leaving behind a warring Earth flung headfirst into a conflict of mutual assured destruction, the Rangers and the accompanying crew of first colonists are guided on a 40-year journey by an unprecedented artificial intelligence. But when they emerge from the frigid embrace of cryosleep, they awake to a nightmare, finding themselves greeted by the same ruthless enemy that brought about the ruin of Earth. 

The Merry Band of Pirates are in desperate trouble after the end of their last mission, and the real danger to humanity is just getting started. Hostile aliens have discovered there is something odd going on with wormholes in the galaxy, and their investigations could lead to finding a shortcut to Earth....

Eight years ago, an engineered virus ravaged the globe, infecting and transforming humans into apex predators called Variants. Now, almost a decade after the end of the war, civilization has slowly clawed toward recovery. But evil and intelligent forces dwell in the shadows with the starving beasts, scheming to restart the extinction cycle and end humanity forever. And once again, Beckham, Fitz, and Kate will rise to fight them, joining forces with new heroes to try and save what’s left of the world.

Lieutenant Magnus survives the harrowing rescue of his unit only to find himself charged with treason by the very military he’s pledged his allegiance to. Now, he must attempt to escort Piper to the Luma, homeward of Worru before dark forces discover her otherworldly abilities. But once there, Magnus finds himself confronting new enemies in the place he least expects to find them. Meanwhile, Awen uncovers a new plot that threatens to upend order throughout the galaxy. She and Magnus find their way to an alien world where they must work together to build a new team from the ruins....

The government said the Variants were dying off.... That the beasts would be extinct in a matter of years.... That the Allied States had returned to prosperity and freedom.... The government was dead wrong. Deep under the cities, the Variants weren't just hiding, they were breeding. While the human survivors of the Extinction Cycle built outposts and brought back industries, the monsters were building something of their own.

After the Renegade mission by the crew of the starship Flying Dutchman, the UN Expeditionary Force thought Earth was safe for hundreds of years, at least. After there was trouble on the home front and the president had to authorize a nuclear strike on an American city, UNEF decided they did need the Merry Band of Pirates again. So, the Flying Dutchman is sent out on a simple recon mission. But for the pirates, nothing is ever simple, and their mission will become Armageddon.

The Alien Legion has a new mission, and this time, they are working for the enemy. Also against the enemy. Like every operation that Emily Perkins plans, it’s complicated. But plans require good intel, and when the plan falls apart, the Mavericks are in freefall.... 

On the island of Big Tancook, Collie Jones is making plans. She informs the islanders that it’s time to resume her original mission - to find other survivors, screen them, and return them to the island. Every survivor she brings back is one more valuable addition to the skill and gene pool. But first, she must return to the place whence she came. She must secure the elaborate government bunker called Whitecap and its vast stores of munitions within.

After Lieutenant Magnus awakes from the orbital strike that nearly killed him, he discovers that a small contingent of his Marine platoon has also survived. Hope glimmers as he devises a plan to rescue them. But when Magnus learns that his men are being held hostage by a deadly tribe, he fears the worst. Aided by volunteers from a group of elite Marauders, Magnus must attempt to cross the hostile city of Oosafar. Time is running out...and he has no choice but to undertake the most deadly urban assault of his career.

Beyond the reach of the nuclear infernos, the masterminds survived and continue their assault on outposts across the Allied States. Timothy Temper and Sergeant Ruckley narrowly escaped one of those attacks. On the run from hostile forces, they fight to get an urgent message to command - the monsters aren’t the only threat. Their human allies have a nuclear weapon. Refusing to hide underground, President Jan Ringgold heads to New York. Doctor Kate Lovato and her team are there working to infiltrate and sabotage enemy communications.
