When Cyndra Raine inherits her grandmother's crystal, she inadvertently awakens a lethal elemental force she doesn't understand. Panicked and desperate, she flees the safety of her village, determined to find answers only to run into a man named Rune with the same abilities and questions. Zorin has spent twenty-five years soaring over his island waiting for something, anything, to change. After sensing caster power he can't ignore, he leaves the island and finds two casters under attack on the mainland. He's shocked to learn Cyndra and Rune are ignorant of their lineage and the war that destroyed the world. Intrigued by Cyndra and the immense power she possesses, Zorin promises her the truth about the past in exchange for her help. Inexplicably drawn to the winged man, Cyndra agrees to his terms and together they begin a journey that tests everything she knows about her world and discovers a connection to Zorin more profound than any she's ever imagined.
