The Earth is no more. Escaping the premature nova of Sol, humanity's last survivors flee their doomed home using an experimental drive that takes them to the far side of the galaxy.

With ten thousand survivors, dwindling resources and rapidly diminishing hope, the fleet is on the verge of breaking point. Gaia, their new home, offers one last chance of survival for the human race.

But when Major Tom Merrick and Captain Juliana Curran lead the expedition to explore this new frontier, they learn that Gaia is a world fraught with peril and deadly secrets.
