Every designer has a pile of covers somewhere that weren't quite right for whatever client one happened to be working for at the time. I'm no exception. To the right you'll see my gallery of covers that didn't make the cut. Some of these are covers I did just for fun, too.
The Fallen Angels series of covers may eventually get used. I don't know. It's a series of covers I did purely for fun with the permission of the cover model, Heather Miller.
