English composition and grammar Book

As tedious and horrible as this book was to complete, it was worth every second of the time. The guide is a comprehensive look at English grammar that covers just about everything that you need to know. It was not as entertaining as, say, Eats, Shoots, and Leaves but this is a book for school and not a guide for the casual reader. The exercises were dull as anything, but I can tell you that I will no longer be mistaking "Who" or "Whom" any more.
