As has been documented, Foley wrote this book by hand after rejecting what a ghostwriter did at first. As a result, it is not the smooth style of a professional - which is not entirely a bad thing. This personalizes Foley's book.
Foley's book is a very good read for wrestling fans and a fairly good one for non-fans. His story telling makes it suitable for those who are not "in the know." The main criticism of the book I find is that it was a bit choppy, which can confuse some readers. This is due, of course, to his inexperience as a writer.
All in all, a great rookie outing, although he misspells Bret Hart's name throughout.
