If she were a normal fifteen-year-old girl, Ivy Nimiki would only be worried about getting her driver's license, arguing with her dad, and finding time to spend with her friends. She wouldn't be losing sleep over her sudden lack of storm control, the inevitable curse that will claim the life of the boy she loves, and her nightmares of the Great Horned Serpent. Ivy never has been, and never will be, normal. It's up to her to find an amulet to defeat the Serpent and end the curse. But how can she do that when the Thunderbird has disappeared? She needs the strong wings of thunder, plus the three newest members of the clan. Gabe's touch affects her like no other's, Cal's heart keeps time with hers, and Dan's soul holds her together. When falling in love, do you listen to your body, heart, or soul?
