A young woman searches for truth in a dying magical world with the help of a cursed unicorn prince in this transportive fantasy from Pulitzer Prize finalist and New York Times journalist Sarah Maslin Nir - perfect for readers of Peter Beagle, T. Kingfisher, Hannah Whitten, and Katherine Arden.

A century ago, man perpetrated a sin against nature, devastating the magic that supported life for all creatures. The sun is dying, its light is extinguishing, and every day for both human and fae is a struggle to survive.

Thea is an orphan, unaware of her origins, but a gifted storyteller. Writing in The Crescent, Thea captures the beauty and wonder of a vanishing world of mystical and mysterious beings that, for some reason, trust only her to share their tales. And when she crosses paths with six wild white stallions, Amalthea meets Prince Arrowyn, the man responsible for this Age of Unravelling who needs her help in restoring the land.

Arrowyn was cursed to to circumnavigate the globe for a century in the form of the creature he betrayed- not a stallion but a unicorn shorn of its horn. Freed at the moment he and Thea's lives collide, the prince believes her mysterious bond with the magical fae may be the key to saving the world.

Drawn to the quixotic prince, Thea joins a quest that spans the realms of elemental magic where they seek to rally the powerful Olde Magic creatures to their cause: selkies, dragons, and harpies, who may know how to heal the bitter sun. Thea is soon torn - is she really falling for the villain who ruined the world? The fae believe Prince Arrowyn's soul cannot be saved-and, horrifyingly, neither should the rest of humanity. It will fall to Thea, her enduring hope and her true purpose on this journey, to save the man she can't help but love and heal the fractured world . . .
