Killashandra, one of the most gifted singers on Ballybran, is drawn like a magnet to the song of crystal. In order to work with crystal, singers are infected with a symbiotic life form that heals them and gives them near eternal life-but slowly destroys their memories. Since crystal singing brings Killashandra ecstasy, she doesn't mind the initial small annoyances of memory loss. What she hadn't counted on was the loneliness she felt when her heart still remembered what her mind had forgotten-the names of her friends and lovers. Can the crystal that destroyed her memory somehow restore it? By reclaiming her unpleasant past, can Killashandra step forward into the future?
