Seventeen-year-old Alison McKye isn't normal--in fact, she isn't even human. She's a Dewing, the offspring of descendants of Atlantis, left to grow up in the care of humans. She also has mental abilities that she doesn't understand. After a chance encounter with another Dewing who warns her that her abilities make her dangerous to her adoptive family, Alison tries to make herself as invisible as possible, drab and friendless. That is until she meets Ian and Brandy, and her life is turned upside down overnight.
