The Selkie Sorceress (Seal Island Trilogy)

She would do anything to protect the people she loved...American detective Sam Holt has a knack for finding people who shouldn't be found. When his last case almost killed an innocent woman, he swore off detective work forever. But when this same woman asks him for one last investigation--to find her husband's long lost mother--Sam cannot refuse. Clairvoyant Irish artist Glenna McClure will do anything to stop Sam, even if it means teaming up with a powerful sorceress who she knows she cannot trust. But when the petals of a mysterious night-blooming rose begin to turn black, Glenna realizes that an even darker force is at work. To protect the people she loves, Glenna will have to face a terrible curse that has haunted her all her life before the final petal fades to ash.
