Spaceships in the Desert — Kristine Kathryn Rusch

Laurel helps many people who return from the desert shaken by what they've seen -- or think they've seen. But Mark seems different. He listens to her, and he makes her obsession with finding the strange silver objects -- and discovering their secrets -- his own.

But that obsession comes with a cost: one neither might want to pay.

“Kristine Kathryn Rusch is one of the best writers in the field.”
