Days of Grass — Tanith Lee

The free humans lived underground, secretive, like rats. Above, the world was a fearsome place for them -- the open sky a terror, the night so black, and the striding machines from space so laser-flame deadly.

Esther dared the open; she saw the sky; she saw the Enemy. And she was taken -- captive -- to the vast alien empty city. Surrounded by marvels of a science not born on earth, Esther did not know what they wanted of her. There was mystery in the city, dread in the heavens, and magic in the handsome alien man who came to her.

Tanith Lee, winner of World Fantasy Awards, crown princess of high fantasy, has turned her talents to science fiction in DAYS OF GRASS -- with the same color and art and suspense that mark all her wonder works from THE BIRTHGRAVE to DELUSION'S MASTER.
