It was The Wyvern.
I remember reading about wyverns a few years ago in the chronicles of the summer king (book series) by Jess E. Owen. Very sweet memories. It is still one of my favorite fantasy book series. I have the first four books in signed hardcover. The fifth book is paperback, and not signed.
Oh that sounds cool! I have not heard of that author. I love a good old Wyvern in a tale. Itys a great word too!
