Only the elders of the Valley remember life the way it used to be, when people travelled in cars and bought food others had grown. When the ratio of male to female 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, the Valley's chief protector, as fierce and loyal as the guard dogs she trains. When an unexpected convoy of strangers rides into her village, it is Dian who meets them, ready to do battle.
