At the top of the BYC home page on the far right side is the "store". You can pre-order yours there. I ordered mine a few hours ago!
When you get there look to the left and click on the book nook
Those are some gorgeous pictures!! I couldn't get Sandiegochickens' link to work, but the rest are amazing! ( and that one probably is too, I just can't see it yet).
Good job picking the winners! I'll have to up my photography game for next year.
