Just noticed today that Everything Goes is up for order on Amazon dot com. There's something that feels "official" about that, now, with the cover image and everything. Official publication date is 13 September. Getting closer every day.

(I really like that it lists its "Best Value" partner book as The Astonishing Secret of Awesome Man. I've never heard of this book, but I love Michael Chabon. I'd order both and get that 5% off if I were you.)
