"A timely, sobering message about how humankind's treatment of the environment impacts the environment's treatment of humankind."—Publishers Weekly, starred review

Ash arrives in Snowflake, Arizona, and finds a small community of people who are sick, including Ash's stepbrother, Bly. But it isn't any ordinary sickness: modern life is poisoning them, and when Ash too falls ill, the doctor's response is, "It's all in your mind." Meanwhile, the world beyond is succumbing to a breakdown of civilization only distantly perceived by Ash and the isolated residents of Snowflake, from which there may or may not be a chance for recovery. This humane and thoughtful novel explores the resilience of love and community in the face of crisis.
