Query: This book did not focus on reviewing IFR flying.

I was disappointed in this book especially since the title contained the word "Refresher". Instead of the book focusing on IFR flying and new techniques, the book turned out to be a collection of short stories and dialog about IFR flying as told by the author.For a better "refresher" on IFR flying, I would recommend "Instrument Flying" (4th edition) by Richard L. Taylor, which is better orgainized, and does give tips on the art of instrument flying.
