I posted this as a book we would read and discuss mid August. Some have noted that it is out of print and on Amazon, listed for about $45 used. Clearly not within reach.
For your information, on Powell's Bookstore's website (my favorite place in all of Portland), they offer an Adobe version of the book for $15. It can be downloaded and read on any computer or handheld that opens Adobe. While reading on a computer may not be the world's best option, I think you will find this book well worth the effort. (It is also available on a Kindle from Amazon for about $9, but if you don't have a Kindle the Adobe option is best.)
