This story is about a woman named Raven who was forcibly mixed with a demon by sorcerers who wanted to make better soldiers for the City State. She lost all of her memories and had to kill and carry out other missions for her masters. When she got pregnant she faked her death and hid. Years later she was discovered and set off to find her team mate and lover to find out who wants her dead. She finds out she was betrayed by the one she loves and starts having flashbacks of her life before her transformation.

There is a lot of action in this book which I loved. Sometimes the plot could seem chaotic but I think it's because there was a previous series set in this world that I haven't read but maybe will check out. This was an enjoyable read.
