I'm the editor of the series that this book is published in. You can actually buy the ebook for $30 at <a href="http://www.morganclaypool.com/doi/abs/10.2200/S00629ED1V01Y201502WBE011?journalCode=wbe.1" rel="nofollow">http://www.morganclaypool.com/doi/abs/10.2200/S00629ED1V01Y2...</a><p>It's a pretty fair price for a 200 page book that's (well in my opinion) interesting.
