Califia's daughters
(Book)

"Only the elders of the Valley remember life the way it used to be ... when people traveled in automobiles and bought food others had grown. When the male-to-female ratio was nearly the same. Before the bombs fell, and a deadly virus claimed the world's men. Now civilization's few surviving males are guarded by women warriors like Dian. When an unexpected convoy of strangers rides into her village, it is Dian who meets them, ready to do battle." -- back cover.
