This is an essential handbook for any grammar Nazi. Prepare to have many persistent doubts dispelled and nagging questions settled - not only about grammar and spelling, but also pronunciation (including that of the word "pronunciation"). This book will help you feel even more annoyingly superior to the uneducated unfortunates around you.
What's more, the sample sentences in the book are almost worth the price by themselves. "A gradual crescendo in the percussion section reached a climax that woke the audience." "When he's not fighting crime, Bruce dresses like a normal adult."
These days, as our entire nation has forgotten the use of the apostrophe, everyone could use at least one grammar book on their shelves, and I can't think of a clearer and friendlier one than this.
