Death or Immortality … Cassidy chose death. Cassidy Daniels hates being a Furor. First, there is the hellish rage that storms through her veins, urging her to kill. Then there is the gnawing guilt, the nightmares, and the pretense. Unfortunately, her sister wants to be immortal. To do so, she needs Cassidy's help to find the Source, an ancient pool hidden beneath Scarlett Valley. When they arrive in Scarlett, Cassidy intends to find the Source and get out, but then she meets Sebastian. Everything about him makes her rethink her choice. There is just one problem. The choice between death and immortality is no longer Cassidy's to make. There are pretenders everywhere, with dark pasts and even darker plans.
