Query: Not bad for folks who don't mind struggling with language and concept -

I was looking for something fresh and interesting, but did not find it here. It suffers from a problem I find in many books of this genre; the author wastes so many words talking up his method that his passion dies down before he gets to the subject matter. If you are a beginner, the books by Fincham, La Rue, Mahabal and the brilliant Richard Unger will take you a lot further a lot faster. If you've already gotten the basics, those books will offer new insights or fresh perspectives. This one asks you to throw out your system, but does not offer much to replace it with.
