When village herbalist Liora rescues a wounded stranger, she discovers he is Caelan, the elven prince of Sylvaris. Bound by an ancient life debt, Caelan vows to serve as her husband for 365 days—but their growing love awakens the Amber Heart and reveals Liora’s hidden Sun Elf blood. Hunted by monsters, threatened by a jealous fiancée, and forced toward a deadly royal wedding, Liora must uncover a five-hundred-year-old lie before the Abyss consumes three worlds. To save humanity and Sylvaris, she and Caelan must choose love freely—even if it costs them their magic, their crowns, and their lives.
