War Girls

Ain't no cold like the cold of warBy 2058, both the Sino-American War and the Sterility Epidemic have decimated the male population. Electricity does not function in five western states. Collectively, they are known as the Juniper.
It is the most dangerous place on Earth.
Cavatica Weller has lost everything. Her home. Her family. Her courage. She's back in the World, in Kansas, where she has electricity, friends, a life, only being alive feels like being dead. She made a deal with the devil and she needs out. Her only hope is her wit, her rage, and a host of new allies.
Once more, she must return to the Juniper Wars, in search of an ex-president and the location of the secret ARK facility. But this time, she's not herself, and the woman she is becoming might kill everyone she's ever loved.
