It is totally your fault that I just spent 15 minutes tracking down the Diane Duane books on half.com :D Fortunately, they were available for less than a bazillion dollars. (Darn it, I wanted to buy them for the Kindle so that Diane would get some royalties, but they're not available. Grumble.)

However, thank you for this interesting post and I look forward to reading the books, so thank you :D
