About the Book"Somewhere," muses Noah Calhoun, while sitting on his porch in the moonight, "there were people making love." Anyway, head elsewhere for Great Literature, but if you're in the market to get your heartstrings plucked, look no further. The Notebook, a Southern-fried story of love-lost-and-found-again, revolves around a single time-honored romantic dilemma: will beautiful Allison Nelson stay with Mr. Respectability (to whom she happens to be engaged), or will she hook up with Noah, the romantic rascal she left so many years ago? We're not telling, but you have two guesses and the first one doesn't count. Decades later, after Allison develops Alzheimer's, her beau uses "the notebook" to read her the story of the great love she's plumb forgot. The Notebook--film rights already sold, thank you very much--is a little glazed doughnut of a book: sticky- sweet, satisfying, not much nourishment. But who cares? Take an extra vitamin and indulge.
