Query: Unusually good fish cookbook

Despite its low price on Amazon, this is a standout fish cookbook. One of its notable features is that the index cross-references similar fish. For example, if you happen to have red snapper, you'll find that the index points you to some very good recipes for striped bass and grouper that work well with the snapper. The recipe for salmon with fresh basil sauce by itself is worth the price of the book.
