In a world devastated by climate catastrophe and competing for dwindling resources, Space Vault: The Seed Eclipse centers on Teagan Ward, a mother determined to protect her bioengineered daughter from the ruthless forces that created her. Diana, born to survive the harshest realities of deep space, holds the genetic key to humanity’s future—and powerful corporations, AIs, and alien factions will stop at nothing to claim her.

Summary: Early in the twenty-second century, many scientists realized that unrelenting global warming would render the Earth uninhabitable within 100 years. Having no viable planet for human migration in the Solar System, the far-sighted Chinese Space Agency plans to send a human expedition to the Earthlike exoplanet Teegarden-B, 12.5 light-years from Earth, to explore it as a potential for humanity to survive. The problem is that no human could survive that long a space voyage with their present technology, thus they decide to clone a human brain into a robot specially designed for space travel and exoplanet exploration. To assure success, they recruit Dr. Victor Wollstone and his wife, Sara Pang, the only people to have successfully written a human brain into a robot body previously, to help them. The mission is fraught with risk as the development team strives to launch it in time to get the data they need to save humanity while they battle anti-brain-cloning activists and anti-Chinese moles and saboteurs, and deal with the growing global panic due to the accelerating collapse of Earth’s ecology. When the expedition does finally make it to the destination planet, the human brain-controlled robot is astounded at what he finds. Can the human race get there and survive?

Summary: They told him the Lette were monsters. But the truth lies buried on a dead world—and it’s far more terrifying. Commander Zane Renner awakens alone aboard a vast, silent colony ship orbiting the planet Artemis. The crew is gone. The only others aboard are a woman driven to madness—and a Lette, one of the alien race humanity has been at war with for decades. Zane has always believed the Lette started the war. But when he descends to the surface and uncovers the haunting truth behind the colonists’ deaths, everything he thought he knew begins to unravel. A failed alien experiment. A world-spanning mind. A virus that could doom the entire galaxy. And a war that may never have needed to happen. Guided by the being he once called an enemy, Zane must confront a devastating reality: the danger isn’t the Lette. It’s what lies below—and within humanity itself. To stop the threat from spreading, Zane must forge an alliance with the last being he ever thought he could trust. In doing so, he’ll uncover a truth buried beneath generations of lies: the Lette never wanted war. Brothers of Mind is a gripping sci-fi thriller about alien contact, dangerous truths, and the courage to rewrite history. Sometimes the greatest enemy is the lie we’ve lived by. And sometimes the only way forward… is together.

Summary: The planet Ardulum has died and taken with it every last andal tree, and piece of andal cellulose tech—dissolving the Alpha Plane down to lightspeed travel and archaic communication. Yet Ardulum’s consciousness still lives, unwelcome, inside Atalant’s body. But two consciousnesses cannot share one host—especially not when one is a former planet. Amidst the remains of a shattered galaxy, Guard Four and the Keft scrapper Bell chance a return to the Neek homeworld, where andal is still rumored to grow. A stable forest of andal could power the Cell-Tal technology to save Eld Atalant's life. Instead, Guard Four and Bell find a populace grappling with the aftershocks of Ardulum's death, and find Ardulum’s genetic influence is wider than they thought. What remains of Ardulum demands a new body of its own, and transport to a mysterious world of Thesby, where a stable bridgeway to another dimension is rumored to exist. Emn, desperate to save Atalant, promises to aid Ardulum in return for healing her wife's battered body. If Emn can avoid Chartered Systems assassins long enough to get to Thesby, she stands to not only be reunited with Atalant, but to rid the galaxy of Ardulum, forever. If she fails, the Charted Systems will remain in the dark ages of space travel, and Eld Atalant of Ardulum, and her vision for the Neek people, will die. Read the sixth book in the bestselling Ardulum series, by J.S. Fields!
