The Sinners of Erspia — Barrington J. Bayley

The Sinners of Erspia are the inhabitants of a bizarre world, ruled and guided by the hands of Ormazd and Ahriman, twin gods of good and evil. Histrina, a child of Ormazd, is taken by the evil hordes to a camp of terror where she meets Laedo, a man stranded far from his home.

Together they start on a hallucinatory journey to understand and escape from the surreal world that holds them prisoner.
