Author’s Comment
"I am sure no one has noticed this, but so far all of the background colors for all the author pictures like the one above (on the left of this page) have been the same color as the cover for the following volume. If any of you have all the volumes, you should look and see for yourself. There are some slight differences in shade, but the basic color should match up. However, now that we have reached the 10th volume, I have decided that this is a good place to stop! What color will the Volume 11 cover be…? Not even I know."
