Anna Marshall wishes she could be anywhere but Ames, lowa, and anything but a singer and music instructor at lowa State University. She gets far more than she expected when she is magically transported to the world of Erde. On Erde, Anna is no longer just a professional singer, she is a sorceress, potentially the strongest in the whole world. In this world, song is magic, and a wrong note can mean death to a sorcerer. Because Anna has trained for a lifetime to reach the level where she won't miss a note even under the worst conditions, she can sing more powerfully and precisely than anyone else. Anna's power does not go unnoticed. The moment she arrives, she becomes a target: both the political entities, who fear the unknown power she represents, and the sexist men of Erde, who fear a powerful woman, try to kill her. Merely to survive, Anna must learn enough song-magic and enough about Erde not only to ensure her survival, but to create a new life for herself.
