Sixteen-year-old Mia Winterborne is destined to be special. Details are sketchy, though, as her dad disappeared when she was five. Mia only knows that she'll inherit her kickass superpowers on her seventeenth birthday. Helping Mia prepare for her anticipated ascendancy is Loie Bryce, her best friend and eternal sidekick extraordinaire. The girls' intense friendship has never wavered until now, when Andreas arrives in Salcey Ridge. They both fall hard for the British hottie, who quickly becomes a fixture in their lives. When they discover that Andreas is not who he appears to be, the frightening reality of Mia's powers finally hits home. The nearer Mia's birthday draws, the more the danger escalates and long-buried lies are exposed, putting the girls on a path that they never expected.
