The immense ark-ship Odyssey and its ten thousand hibernating settlers have left behind a dying Earth-journeying for fifty years to the nearest star and its lone habitable planet, Proxima-b.

This new home for humanity is perpetually bombarded by deadly solar flares on its dayside, while the icy wasteland on its opposite hemisphere freezes in endless darkness.When the battered Odyssey arrives, its crew discovers the automated radiation shield has failed. Something appears to have damaged or perhaps even sabotaged their technology on a world where humans have yet to set foot.

Astronaut Darcy Clarke, a young pilot born aboard the Odyssey, teams up with recently awakened engineer Tanya Baxter to repair the failing shield in hopes of allowing the colonists to land before their vessel falls apart.Waiting for the two explorers on the surface of Proxima-b is the geoglyph-a continent-sized landform that resembles a giant metallic work of art.

Is it a massive ore deposit, an alien message, or something far stranger and vastly more dangerous? Or perhaps even sabotage for their technology on a world where humans have yet to set foot?
