I was recently recommended to look for a book called, "Sharpened Edge", by a pilot I know who swears by the series and recommended I give the PPL version a read prior to my test. So of course I went online when I got home to try and find a copy and checked my local library, but to no avail.

I was wondering if anyone who has read this book can tell me if its worth the search, and if so, if by any chance they knew who the author was. As i'm sure many pilots in the infancy of their training, finding as much info to help learn the topics, especially the really important ones, sort of becomes an unending quest.
So as always, I appreciate the help and look forward to the replies!
