Over two hundred years after the first colonists landed on Pax, a new set of explorers arrives from Earth on what they claim is a temporary scientific mission.

The Earthlings think the humans are in charge of the settlement, dismiss the Glassmakers as pets , and fail to understand that the sentient plant, Stevland, is in charge. Even as Stevland attempts to protect his humans from the intrusion, a more insidious enemy than the Earthlings makes itself known.

The humans and the Glassmakers weren’t the only colonists on Pax, and this new arrival has no desire for peace-only conquest.
