The We walk among us - beings who existed long before humans ever did, filled with powerful magic. They are known as angels and the fallen are known as demons. Demons long to be returned to the Divine, and the only way back is ethereal magic found in music. Some humans are born with ethereal magic and their voices have divine power - humans like Alice and Owen. But Alice is bound to a demon who will stop at nothing to use her for his purposes, and Owen and Alice must destroy her connection to the demon in order to be together.
