As the son of Zephyr and Avani, Ancalagon is the last pure dragon. Because of his time in a scientist’s laboratory, he not only has the air and earth elements, but also fire and water, making him the only dragon in history to have all four elements. However, the scientist created a flaw in Ancalagon's DNA. If he isn’t claimed by his mate, he could lose his humanity. Eliane is the daughter of Oliver, the scientist who tortured Ancalagon. She, herself, was experimented on, never seeing the outdoors until the night the dragons came for Ancalagon. When Ancalagon tried to rescue her, Oliver snatched her away and for months he tortured her in the same way that he'd tortured Ancalagon. Eventually, Eliane believed that Ancalagon left her to suffer at her father's hands. When she finally escapes, Eliane runs, trying to hide from all supernaturals. She begins having blackouts, large periods of time where she has no recollection of what happens to her. It’s during one of these blackouts, that she meets Snow, another dragon. They become friends and begin helping each other, protecting each other from the bad hybrids who are hunting them. When Snow shifts, telling Elianne that his name is Iniko, he leaves a strange mark on her, his image over her heart. It forges a deeper connection between them and when the bad hybrids capture him, she runs to the elemental dragons for help. What will happen when Ancalagon realizes that his brother has been claimed by his mate? How will Eliane react when she realizes that Ancalagon has been searching for her all this time. Will she be able to heal his broken DNA and help him regain his humanity, or will she leave him, breaking what's left of Ancalagon?
