Human survival on another planet hinges on a bizarre alliance in this character-driven debut science fiction novel of first contact.

“Combines the world-building of Avatar with the alien wonder of Arrival, and the sheer humanity of Atwood. An essential work for our time.” —Stephen Baxter, award-winning author of The Time Ships

Colonists from Earth wanted the perfect home, but they’ll have to survive on the one they found. They don’t realize another life-form watches . . . and waits . . .

Can humans learn how to communicate with the planet’s sentient species and forge an alliance to prove that humans are more than mere tools?
