Adult Fantasy Novel - Villain turns into bird at the end.

[Alan]

Fantasy Paperback. Villain turns into bird at the end, forgets who he is and flies away.

The cover had either crystals or elements (earth, air, fire and water) - on the corners of the cover.

I do not think it was part of a series.

Thanks.

Alan, around what year did you read this book? A range of year is fine.

Is this book for adults or teens?

Can you tell us more about the plot and main characters (e.g., ages, genders, jobs, powers)?

I can barely remember anything else about the plot. I think it involved crystal technology.

This was adult fantasy. Tor may have been the publisher. I think I read it around 2004.
