Through

Three and a half centuries ago, a generation ship left Earth and was written off, forgotten. But now it arrives.The Able is too fast to stop. If it does not get ripped apart by the star it is bearing down on, it will keep going, through the system and into interstellar space. Gone.On board, a geologist wakes from cryosleep to find himself the only survivor who remembers Earth. He is alone among tribes of people who have never seen a sky, who keep their failing vessel alive with ritual and chant, and who have no word for horizon.The colonies of 18 Scorpii are in no condition to help. They are a handful of thinly settled worlds, counting every resource twice, their fragile economy leaning on a computer older than anyone alive. And they are busy surviving the Sisters' Kiss, the once-in-four-generations event when two planets swap orbits, bringing violent beauty, raging storms, and broken communications.No one has time, or capacity, to care about the Able. Only an Elder, who has outlived every friend he ever made, trades his retirement for one last negotiation.A pilot who breaks protocol the way other people breathe gets her hands on the fastest ship ever built to attempt something that cannot be done.Three trajectories. One window. And the slow realization that humanity's greatest adventure was never the journey outward.It was refusing to leave them out there. Hard science fiction with philosophical weight and genuine heart, for readers who need their space opera to mean something.
