Query: A disappointing book, however brilliant.

Often, I've sat reading this book in bookstores across Boston, hoping for it to change its ways. It's brilliantly organized and the pictures are great, but the knowledge behind the framework and fandango is either absolutely lacking or off for a lunchbreak. The author totally ignores the differences between the English and American A&C aesthetics, which, if you are already familiar with the differences, might not make much difference, but if you are a newbie to the A&C Renaissance, will be hugely misleading. The architectural poetics espoused by Morris and Voysey are quite different from those of Stickley, Wright, and the Roycroft community. I would have expected much better from this author.
