I'm also thrilled that translation rights are being picked up.
The list so far:
USA (Simon & Schuster)
France (Editions Jean-Claude Lattes)
Germany (Goldmann Verlag)
Italy (Sperling & Kupfer Editori)
Holland (De Boekerij)
I'm told that in France, 'oink' translates as 'groin', so that's going to be an interesting edition.
