Free as in "You don't pay for it!"

A while back Neil Gaiman ran a pole to find out which of his novels people would like to see online for free.
I was a bit dubious but it turned out that American Gods won and is now available free on the Harper Collins website. Some people may already know about it, some people may not care, but if you want a chance to read a great book about mythology for free (but we don't know for how long), head on over and have a look (or a Loki).
I've been very lucky with these books, a really good friend over in America got me a signed (and personalised) first edition of American Gods! I'll still read the on-line version, if only for something to do in work.

*editted to add* Apparently the free book is only up for this month (March!) so enjoy while you can!
