I have read it. The book was ok, had some good ideas and suggestions, but he had a tendency to preach too more than I cared for. Personally, wait until your bee club has a copy to lend out rather than spending the money to purchase it. You can get all of the same info here on the forum or in other books. Just my opinion.
There are a couple of other books that I read recently that had good info in them IMO: Hive Management by Richard Bonney and the other one was Increase Essentials by Lawrence John Connor. The latter is a bit more difficult to read at times but gives good info.
