Winter's love is blood and chaos...but fire isn't all that smolders at Summer's heart. To claim Bran forever, Macsen has begun the ancient ritual of sidhe courtship-but such a rite is a trial in more ways than one. Tradition requires that Macsen seek Bran's favor in his own country, and a Summer courtship is teasing and promising. More than that, Summer's Queen will come between Macsen and her son however she can. Despite his mother's disapproval, Bran's will is bent to the same purpose as Macsen's-the achievement of four proofs of love, proofs that only Bran can determine or acknowledge. One step at a time, they come closer to a day when nothing will be able to separate them-but a familiar foe is more than willing to try. In the mortal world, the year has continued to pass without a hint of green. The Green King has prevented the spring, and thus all seasons but winter. Still, it's Macsen whom Dealla blames, and all her plans for violent retribution are directed at him. Failure may cost her everything, but that is a price she has long been willing to pay. In the wake of her invasion, Macsen is left with a dilemma that might not be easy to solve. Love, or vengeance-which should he choose? Can they live together in the same heart?
