Sanctuary: The Go David Chronicles Book Two

Go David was engineered to reach distant stars, not to question his purpose. When he tries to change his fate, he's rejected by those he loves, and by those he thought loved him. In the aftermath, he slowly accepts his reality and adopts Marcus, a thruman child born in a machine.

Together, they continue their journey to Orion. But survival soon demands more than endurance. It demands reinvention. As Go and the crew brave a hostile frontier, they learn that sanctuary isn't inherited, it's made from memory's wreckage, and the courage to begin again.
