AMY AND ELDER have finally left the oppressive walls of the spaceship Godspeed behind. They're ready to start afresh-to build a home—on Centauri-Earth, the planet that Amy has traveled 25 trillion miles across the universe to experience.
But this new Earth isn't the paradise that Amy had been hoping for. There are giant pterodactyl-like birds, purple flowers with mind-numbing toxins, and mysteri-ous, unexplained ruins that hold more secrets than their stone walls first let on. The biggest secret of all? Godspeed's former passengers aren't alone on this planet.
And if they're going to stay, they'll have to fight.
Amy and Elder must race to uncover who—or what-else is out there if they are to have any hope of saving their struggling colony and building a future togeth-er. They will have to look inward to the very core of what makes them human on this, their most harrowing journey yet. Because if the colony collapses? Then everything they have sacrificed-friends, family, life on Earth-will have been for nothing.
