Angus McCraggan sacrificed his life to break the Celtic curse laid upon his people in the Bronze Age. He failed. Millennia later, he returns to modern Ireland to find his people have become feral, vengeful shadows. With his hollow hill now a tourist attraction, he uses his power to keep his past hidden. Until an American calls him out... Since a banshee attacked her as a teen, Erin De Santos has been tormented by dreams of a boy she's never met. Armed with a new identity, she returns to the Emerald Isle determined to face her nightmare. But her discovery turns fatal. When the banshee strikes again, Angus surrenders his heart-and his hope of freeing his people-to save her. With his life now hers and his curse descending, Erin must make a terrible choice: kill her savior or share his doom.
