On the planet known as Snare, the descendants of Islamic fundamentalist emigrants have created beautiful enclaves, where they can sit on a patio enjoying green grass and "true-roses," but the nomadic tribes live in a much harsher landscape. There the grass is purple, the trees are orange, and the huge and dangerous sentient Cha'Meech lizards roam the landscape.
Idres Warkannan and his companions are on a quest through this landscape, looking for the only man who can redeem their Islamic civilization from its despotic ruler and restore justice to the population. Zayn Hassan, refugee from the despot's service, finds himself living among the tribes of the "comnee," where Healer and Spirit Rider Ammadin, seeing the dangers all around her, is beginning to doubt the gods who are her only protection.
To save herself and her people, Ammadin journeys eastward into war, intrigue, and adventure-and finds more than she bargained for on all counts.
