Summary: Life after the Crash. Over a century after the end of the Earth, life goes on in Redemption, the sole remaining Lunar colony, and possibly the last outpost of humankind in the Solar System. But with an existential threat burrowing its way into the Moon's core, humanity must recolonize the homeworld. Twenty brave dropnauts set off on a mission to explore the empty planet. Four of them—Rai, Hera, Ghost and Tien—have trained for two-and-a-half years for the Return. They're bound for Martinez Base, just outside the Old Earth city of San Francisco. But what awaits them there will turn their assumptions upside down—and in the process, either save or destroy what's left of humanity.

Summary: Liminal Sky chronicles humankind's first journey to the stars. The first three books - the Ariadne Cycle - cover the creation and launch of Ariadne (aka Forever) as she was grown from seed on an asteroid and then launched across the interstellar void. The books are told in epic fashion, with each broken into three parts that span generations. THE STARK DIVIDE Some stories are epic. The Earth is in a state of collapse, with wars breaking out over resources and an environment pushed to the edge by human greed. Three living generation ships have been built with a combination of genetic mastery, artificial intelligence, technology, and raw materials harvested from the asteroid belt. This is the story of one of them—43 Ariadne, or Forever, as her inhabitants call her—a living world that carries the remaining hopes of humanity, and the three generations of scientists, engineers, and explorers working to colonize her. From her humble beginnings as a seedling saved from disaster to the start of her journey across the void of space toward a new home for the human race, The Stark Divide tells the tales of the world, the people who made her, and the few who will become something altogether beyond human. Humankind has just taken its first step toward the stars. THE RISING TIDE The Earth is dead. Five years after the Collapse, the remnants of humanity travel through the stars inside Forever: a living, ever-evolving, self-contained generation ship. When Eddy Tremaine and Andrissa “Andy” Hammond find a hidden world-within-a-world under the mountains, the discovery triggers a chain of events that could fundamentally alter or extinguish life as they know it, culminate in the takeover of the world mind, and end free will for humankind. Eddy, Andy, and a handful of other unlikely heroes must find the courage and ingenuity to stand against the rising tide. Otherwise they might be living through the end days of human history. THE SHORELESS SEA Rise of the Inthworld. The fight for the future isn’t over yet. It could lead to a new beginning, or it might spell the end for the last vestiges of humankind. The generation ship Forever has left Earth behind, but a piece of the old civilization lives on in the Inthworld—a virtual realm that retains memories of Earth's technological wonders and vices. Lilith leads the uprising, and if she sets its inhabitants free, they could destroy Forever. But during the ship's long voyage, humanity has evolved. Liminals with the ability to connect with the world mind and the Inthworld provide a glimmer of hope as they face not only Lilith’s minions, but the mistrust of their own kind as homotypicals fear what they can't understand. The invasion must be stopped, the Inthworld healed, sothe people of Forever can let go of their past and embrace their future.
