I had to explain a couple of times that the book wasn't coming out until December, and that the cover came from a completely different department, so I had no input into it at all. Except a bit of my synopsis is in the descriptive text on the back (not the back cover copy, the stuff intended for the buyers).
Choir is almost a separate world for me--I only occasionally interact with fellow choristers outside of the group, and then usually it's for other musical purposes, like attending a concert. It's so much a part of me, a basic, inextricable need, just like writing. Yet the two hardly ever meet, and seem to engage different parts of my brain.
