What fortuitous timing. I just began the book myself!

Unfortunately, I was only able to find it on Audible.com (at least for immediate delivery). If you're not up for the hefty online fee, you can always ignore international intellectual copyright laws like most of the Mid E and just download the torrent (it IS available).

Otherwise, you've always got Amazon or Half.com. Works well for me, usually.

Anyhow, it's a fun read...or listen, in my case.

Cheers
