Three hundred years ago, Karma Eliot lost everyone she loved except her brother. On the edge of losing him, she sold her soul to the devil to save him. In that moment, she became a blood demon. Now, she lives in Los Angeles, with her best friend Periwinkle Abcot. Unlike Karma, Peri is an angel. But they wouldn't let that keep them apart. Life had always been simple. Karma did her thing. And Peri did hers. However, when Abigail Williams comes to visit and a demon hunter moves into the area, things begin to get complicated.
