Five crowns. Two reluctant lovers. One throne—and a doorway—between them. Flora Domhnall is determined to protect her people and keep her Highland clan neutral in a war between immortals. Then she finds a dying warrior—one of the rebel king’s Riders—bleeding in her woods. If Queen Vheara’s soldiers catch him, Flora's clan will hang as traitors. If she turns him away, the rebels will demand revenge. Chyr never expected to owe his life to a mortal woman. He's supposed to be immortal, but a mysterious wound is dragging him toward death, and the doorway back to his world is sealing shut. If he misses it, Vheara will tighten her grip on Flora’s realm and turn her conquest toward Chyr's world beyond the veil. Bound by necessity and hunted at every turn, Flora and Chyr cross moor and mountain while the Highlands burn and the ancient land awakens in fury. Flora's magic defies the oaths that bind Chyr, but as her power grows, he needs her to wield it. To save his people and hers, he’ll pay the price in pain and heartbreak. Honor is everything—until it isn’t. Then you hunt for the one chance left.
