Just in case you haven't seen it already, Mother Reader's 48-Hour Book Challenge starts tomorrow at 7:00 AM sharp! (Well, for me it does. For everyone else it can start any time between then and 7:00 AM sharp on Saturday, if they're putting in the whole 48 hours.)
Here's the official sign-up post, and here's the most recent reading of the rules.
Hope to see you there!
