Earth belongs to mankind once again. But not everyone has the same vision for the planet. Dean visits Earth, touring the colonies, and quickly learns that not all remaining humans are pleased with the new changes to their planet. The Restorers are determined to build a pre-Industrial Revolution state, claiming technology will only destroy them again. Dean must infiltrate the group and learn their master plan before they go too far.

The Academy is a galaxy-class school, created to train the next generation of Gatekeepers. Jules Parker is attending the Academy, alongside her best friend Patty. When the Kold threaten everything her father and his friends have spent years building, she must reveal that her Iskios abilities are stronger than ever. With Magnus and Slate away on the Horizon, and Mary working on the board of the Alliance of Worlds, Dean finds himself out of the action for the first time.

The first human exploration vessel has been manufactured. All it needs is a mission. Horizon is a state-of-the-art vessel, a hybrid born of Keppe technology and human innovation. Magnus accepts the role of captain as the new ship is launched on its maiden voyage. Dean’s thrilled to take a back seat on the adventure, but things don’t ever work out as planned for our hero.

As Dean Parker takes a moment to celebrate the successful rescue of Magnus and Natalia, he’s reluctantly forced back into the field, the goal: save the dozen Gatekeepers trapped beyond the failing portals. Karo and Ableen align with Dean and his family, but when an unexpected twist sabotages the mission, their lives might be the cost of returning home. 

Things have slowed down for Dean and Mary as they manage the expanding human colonies on Haven, New Spero, and Earth - until they receive a distress call from the Keppe. Magnus and Natalia are in the midst of a three-year exploration mission on the alien vessel, but mysteriously vanish with less than a year left to go. The portals are failing, making the journey more arduous, and when the crew finally think they know what’s happening, they realize they are also stranded.

Some secrets prefer to stay buried. When Dean’s closest ally is kidnapped by an ancient race, his grief threatens to turn to madness. With the support of his friends, he embarks on a mission to get his loved one back, and stop the eventual destruction of the known Universe. But Dean can’t do it without solving an age-old mystery. He must find the real Theos this time, and he’ll stop at nothing to accomplish that. Join the Survivors as they battle for every race in existence. The Theos is a tale of love, adventure, deception, and above all else: surviving.

“The Theos await you. Only then will we stop the Unwinding.” The threat of invaders is gone, and Earth has been bartered away as a price for peace. Yet, the human world of New Spero is thriving and full of hope. Joining the rank of the Gatekeepers, Dean and Mary set off to explore worlds connected by the mysterious portals. When they stumble upon a strange symbol, they are led to an ancient object, one that sets them on an unstoppable path. The journey takes them through multiple worlds, before they can find what they’re searching for.

A year after the Event, horrific memories of the vessels linger in Dean’s mind as he tries to find his way forward in his new life. But now the heroes of Earth face a new threat that endangers the fragile remnant of humanity. Two rebel hybrids have escaped from their segregated encampment. Dean and his team pursue them across the galaxy, racing to catch them before they reach an unseen enemy. This new threat is looming over Earth, their name spoken softly and fearfully by anyone who knows of them. 

After a surprise visit to Earth, Dean and his crew travel to Proxima Centauri, home of humanity’s first colony world. Once again, Dean’s efforts to lead a normal life are cut short when his sister is threatened by deadly creatures at Terran Five, Spero’s northernmost outpost. There, Dean stumbles on an ancient secret, buried deep in the snow-covered mountains, that will change his life forever. And when communication with Earth ends, he realizes his worst nightmare has come true. The Bhlat have arrived.   

Cities all around the world reported strange alien vessels descending. Some saw them as the heralds of a new age; others fired everything they had at them. All were taken as the beams lashed down and drew them into the sky. Dean was left behind, seemingly the last man on Earth. A trail of clues left by his dead wife guides Dean on a perilous journey across America and beyond to learn the truth behind the mysterious ships and save humanity from its doom.   

Flint, Wren, and Ace, along with Charles, are now members of the Eureka, a state-of-the-art vessel heading for a world in the far reaches of a new galaxy. Sixty years ago a colony ship was sent there, along with someone close to their benefactor. But when they arrive, they find getting to the surface isn’t as easy as they thought. With a crash-landing, and news that shocks the entire crew, they must collectively find a way to get the Pilgrim off-planet and into the fight against the Watchers.

Andrew and Kendra have learned what’s on the other side of the ridge, but it leaves them with more questions than answers. Their colony has turned into a dictatorship under the thumb of its delusional self-appointed leader, the Reverend, making their lives a living nightmare. With a plan in place and help from their new allies, the group plans to sneak out of the colony and make contact with their new neighbors. But nothing in Eden is ever as simple as it seems.

The Concord is in shambles after the return of the Statu, but under the guidance of the Zilph'i, trust is slowly being rebuilt. Thomas Baldwin remains confident in his team, the secrets of his ship and the Concord no longer a dire threat. While the Founders continue to appease the Concord members, the Border Wars are picking up steam, and Constantine is sent to the far reaches of space to the Zilph'i homeworld to request the Ugna's aid.  

Kendra, Andrew, and the other survivors arrive with Lewis Hound’s chosen people at an unfamiliar planet with more questions than answers: how did they get there? Where did all of the advanced technology come from? And is this really Proxima B Centauri? The colony ship breaks into sections and makes an emergency landing amidst a meteor shower, and Lewis Hound, Eden’s enigmatic leader, goes missing.

 Lucky and crew think the worst is behind them when a ship finally arrives to whisk them away from a doomed diplomatic mission. It doesn't take long to learn how wrong they are. Before they know it, a seemingly vanquished foe returns more powerful, and with more resources, than ever.
