Wishes Under a Highland Star (Order of the Dragon Knights) by Mary Morgan

As chieftain for his clan, Alex MacFhearguis struggles with the burden of an unwanted responsibility. With the midwinter feast approaching, he flees his castle to find comfort and solitude within the forest. Yet on his quest, Alex stumbles into a world filled with magic, mysteries, and a woman with beguiling eyes who could capture his heart. When half-Fae Aine Fraser makes a powerful wish, her simple request unlocks the magic she possesses and brings forth a Highlander into her world. Though the man has lost all his memories, she finds her attraction growing for this brooding warrior with each passing day. Unable to deny her feelings, Aine risks everything when she confesses her greatest secret. Can a beauty who wished for a champion tame the beast of Leòmhann Castle?
