Desperate Wishes by Candace Nola

In the not distant future, civilization as we know it is unrecognizable. People are property, and names are stripped away, replaced by obligation. 
 
Mackenna is treated as less than a person, as lesser than a beast. In her pain and rage, she opens herself to a voice that promises the fires of change. 
 
"With Desperate Wishes, Candace Nola offers a glimpse of the terrible through bright and beautiful prose.  She shows that the worst of monsters is what lurks in their very human hearts, and that the line between justice and vengeance is uncomfortably thin.  Be careful what you wish for."  - Mary SanGiovanni, author of The Hollower
