Cillian believes he's immortal—an endless punishment for a betrayal centuries ago. He scours the mortal realm for the lost princess of the Seelie throne, sworn by blood-oath to protect her until his curse is broken by her true kiss. He never imagines the sharp-tongued charm-maker who keeps rolling her eyes at him could be that princess, hidden at birth to protect her from the war that destroyed her family.
As attacks on Cillian grow more targeted and Aoife's magic begins awakening memories she never had—of wings, crowns, and a mother’s lullaby in the fae tongue—their bickering turns to reluctant alliance. Aoife discovers she is Princess Fiadh, the Clover Crown, whose return could reunite the fractured courts. But the same kiss that would free Cillian from immortality would bind Aoife forever to a throne she never wanted—and force her to choose between the quiet human life she loves and the realm that needs her.
Between narrow escapes, stolen dances at moonlit céilís, and truths neither wants to face, Aoife must decide if saving a warrior who has never once said thank you is worth risking her heart—and if breaking an immortal curse means losing the one person who finally makes her feel like she belongs somewhere.
