One touch saved his life; one moon will bind their souls forever. Seraphina is a village healer who knows better than to trust the shadows, but when she finds a colossal black wolf dying from a silver-tipped harpoon, her instincts override her fear. She saves the beast, only to realize she has rescued Lucian, the ruthless Alpha of the Obsidian Pack. Now a "guest" in his gothic mountain keep, Seraphina is caught in the crosshairs of a primal mate bond?a golden thread of fire and obsession that demands her total surrender to the man-beast who claims her as his own.

As fanatical hunters gather to burn the forest to ash, the line between healer and captive blurs into something far more dangerous. Lucian is a king of the wild, cold and possessive, but Seraphina's touch is the only thing that can tame the madness clawing at his soul. In a world where humans and wolves are sworn enemies, they must choose between the laws of their kind and the raw, sensual hunger of the bond. The war is coming, the moon is rising, and in the shadows of the Obsidian Keep, some secrets are worth bleeding for.
