For the record, I am tearing through this thing. I started it on Saturday afternoon and am nearly halfway through it. Of course I was reading into the wee hours of Sunday AM (not non-stop from the afternoon, I took a nap and played Ticket to Ride for a while as well). I'd say Saturday/Sunday I read about 9 hours total. It goes really quickly and is hard to put down.
And I hadn't checked the boards in several days, I had no idea this was the book choice for the month!
