For real this time - lol. And because I keep forgetting it, here's a link to the site: http://24hourreadathon.com/
There are over 420 readers this year, which is awesome and would have made Dewey very happy to see!
As for myself - I started in my time zone (New Zealand) about 5pm-ish. I'm a little way into The Passage by Justin Cronin, and I've read one short story from Everything's Eventual, by Stephen King.
I'm about to go and do a spot of cheerleading, then I'm off to bed for a while with my book.
Have a great readathon everyone!!!
