Jack Tamerlaine hasn't stepped foot on Cadence in ten long years, content to study music at the mainland university. But when young girls start disappearing from the isle, Jack is summoned home to help find them. Enchantments run deep on Cadence: gossip is carried by the wind, plaid shawls can be as strong as armor, and the smallest cut of a knife can instill fathomless fear. The capricious spirits that rule the isle by fire, water, earth, and wind find mirth in the lives of the humans who call the land home. Adaira, heiress of the east and Jack's childhood enemy, knows the spirits only answer to a bard's music, and she hopes Jack can draw them forth by song, enticing them to return the missing girls. As Jack and Adaira reluctantly work together, they find they make better allies than rivals as their partnership turns into something more. But with each passing song, it becomes apparent the trouble with the spirits is far more sinister than they first expected, and an older, darker secret about Cadence lurks beneath the surface, threatening to undo them all.
