Kesh, a dying desert town under two moons. Sefa Kael, a relic salvager, owes the town for every drop she drinks; ten years ago her father went to open the Door in the cliffs and never came home. Now the Door glows, and Cistern Master Orrin Tash means to blast it open when the moons meet tomorrow night. She has one day to cross the Red Reach and get in first. A desert adventure of thirst, debt and inheritance.
