I did it for me :-)
I wanted to change the cover, and this image always felt so right to me. The first dream I had about this story involved a girl flying a giant bird. This drawing by Andy Simmons captures the feel of the "Crystilleries of Echoland". It is a children's fantasy with a complex plot, whose theme is woven into everything.
Here's a glimpse of the old cover. As you can see, they are very different indeed.
