I had very high expectations for this book, given that it was announced as the premier volume in a McGraw-Hill series, endorsed by USAF historian Walter Boyne. What I found was a book that appeared to be a rewrite of Lockheed/Martin's press package on the F-22, often not carefully edited (there are lots of misspellings and fragmented sentences).
Also, having read Bill Sweetman's MBI book on the F-22 and the outstanding Aronstein, Hirschberg, and Piccirillo book (now there is an excellent book!) before this one, I guess Steve Pace's book was handicapped from the start.
In summary, if you can buy only one book on the F-22, this one is for you. On the other hand, if you have a deep interest in the topic, this one may not add as much as you would hope for.
