Aisling

A half century ago a young princess named Anghara opened the door of a dark tower and unwittingly released seven demons. To atone for the evil she'd loosed into the world, she forsook her mortality, took the name of Indigo, and set out on a harrowing quest to vanquish their power. Six demons she tamed. But one remained...Seeking an end to her roaming, the woman called Indigo returns home to the Southern Isles, hoping against hope that Fenran, her long-lost love, still lives. But when a fateful shipwreck deprives her of her memory, her quest goes awry, and the last demon of the Tower of Regrets rises again to tempt her into evil. Only the aisling—the magical tune of an ancient, enchanted harp, has the power to free her from the ancient curse that binds her.
