I came into a free first edition hardcover of The Power That Preserves today.
I was really impressed by the cover - signed by S. C. Wyeth.
I have seen little images of it on the internet, but had never actually seen the real deal before. I am really pleased with it.
Unlike most cover art, with this you can tell that the author had actually read the book, and thought about the contents of the book!
Anyway, this is as good an image as I can find on the internet, but it doesn't show Revelstone as well as the real cover does.
I like this picture of Revelstone, other than it not showing a space/place for the courtyard between the guard tower and the main keep.
Wyeth even put in little bridges between the tower and the keep, though.
