1263, Scotland Simon MacCoinneach's vengeance runs deep. The blade is the only way to end the blood-thirsty Nordmen's reign upon Scottish soil. His soul might be lost, but the mystical Healer he kidnaps from the isles could be the answer for his ailing mother...and his heart. Isles-born Gwyn reluctantly agrees to a marriage alliance with this heathen Scot in return for the sanctuary of her younger brother from her abusive Norse father. Her brother's condition is beyond the scope of her Ancient power, for larger healings steal breaths of life from her own body. As Simon and Gwyn fight to outwit her madman father and a resentful Norse betrothed, Gwyn softens Simon's heart with each merciful touch. Gwyn's Seer sister foresees a bloody battle—and an end to the Nordmen—but Simon will also die. Will Gwyn save Simon on the battlefield even if it means losing her last breath?
