Eats, shoots and leaves

This book on punctuation is really quite humerous, as well as informative. Of course, my own use of punctuation is very poor, but I can sympathize with those who are sticklers. The British perspective, which I didn't previously realize was so different from the American perspective, also added a new a spin to proper grammar. I certainly didn't know that every grammatical "rule" was so open to interpretation or debate. Definitely worth the read whether you're a serious writer or someone who merely dabbles, like myself.
