Curtis Macurdy is a simple, Depression-era farmer married to the beautiful and exotic Varia. Varia is kidnapped and drawn back to her home in the parallel world of Yuulith. Macurdy follows her, but is immediately enslaved. After some training as a shaman, he shows promise as a fighter, and is sent to an elite regiment. He breaks out a few months later with two friends. Soon they fall in with outlaws and Macurdy quickly rises to the top, leading a successful rebellion.
Meanwhile, Varia is back with the Sisterhood, which she forswore long before. The Sisterhood are a sort of cut-rate Bene Gesserit order, with a long-range breeding plan. She escapes and is soon captured by a party of the ylvin and eventually falls in love with the leader.
Moderately entertaining swords-and-sorcery fantasy.
