The Eight by Katherine Neville is being offered as a free e-book until next Monday. I'd definitely recommend it since it is one of my favorite books. (Ignore the cover quote comparing it to The Da Vinci Code. The Eight is a kazillion times better.)
On an almost unrelated tangent, while I was waiting to pick up a package at the local UPS store (which turned out to be an advance reading copy of The Fire, squee!!, ahem), the guy in front of me was mailing out a huge box containing two thousand dollars worth of shoes. I don't think I've even spent half that much on all the shoes I've worn in my life.
I just tried downloading the book. I got nothing. That's okay, I still have a bunch of books I haven't read.
I was at Costco one day several years ago and the guy in front of me was buying like four or five boxes of cigarettes. His bill was $5,000. I was blown away. That small a package was worth that much money. I'm still in shock.
The link to the book is on a weird flash thingie, so you have to click on the link and the entire book pops up on a separate window. Then you can save the pdf file.
And wow about those cigarettes. Aside from all the other reasons to not take up smoking, that's one heck of an expensive habit.
