Query: Very thin book

Bottom line: there's not much to this book. Unless you're a horse race player, which I am not, there is very little useful information. Brokopp provides a few online casino URL's and some background information on the casinos, but there is really nothing in the book that couldn't be found easily on the Web (for nothing). Save your money and skip this book.
