My partner has the first two in limited edition (black pages, covered in dragons, very cool on the bookshelf) but according to QBD the third book was pre-sold out in December, two months before release date. I haven't been able to find it anywhere all week, but Kmart just dropped it a little later AND cheaper than the rest of the crowd so I finally managed to get it shipped :-)
It's also a dollar cheaper than the standard hardback!
Hope it helps some readers or partners of readers :-D
$34 if anyone wanted to know
