Carmen is an angel — a song angel. Her job is to find exactly the right piece of music to lead a human from life to afterlife. It's not always easy. But being an angel? Amazing. Whether soaring above the earth or changing her own little corner of the cosmos, Carmen is hooked.

Then the flashbacks start. There's a baby, there's opera music. Bits of her old life on earth begin to bubble up, threatening to drown her. Add flashbacks to the harassment campaign by Lev, a handsome but tortured song angel, and suddenly life as an angel doesn't seem that angelic.
