Thanks to Teblog reader Kat for sending me a note about pre-ordering "Through My Eyes" on Barnes and Noble's website. She noticed something on the page, and I'll try to explain it:
Apparently, you can get a signed edition, and it's only a dollar more than the standard hardcover price. It also appears to come out a week earlier (5/24) than the standard edition (5/31).
Sometimes bookstore web sites can get these little details wrong, but it certainly seems like something interesting to look into, if you were planning on getting the book.
