You have nothing to lose but your niggling worries if you're haunted by whiches, all tensed up, or baffled by whose and who's. O'Conner, a veteran copy editor at The New York Times Book Review, tells all about the underlying logic of our quirky language. With examples that will make you laugh out loud, O'Conner helps us brush up on our English, making each of a little more literate and a lot more at ease with the language.
