I've summarized dozens of books in my literary career; it's become rather second nature.
Writing long books is a laborious and impoverishing act of foolishness: expanding in five hundred pages an idea that could be perfectly explained in a few minutes. A better procedure is to pretend that those books already exist and to offer a summary, a commentary.
I get to show the reader the essence of the book without giving anything away.
After you've read a novel, you only retain a vague memory of its contents. You remember the atmosphere, the odd image or phrase or vivid cameo.
I'm no good at describing my books. 'Holes' has been out now for seven years, and I still can't come up with a good answer when asked what that book is about.
The first function of a book review should be, I believe, to give some idea of the contents and character of the book.
Books and novels in particular that grapple with quite a few things are difficult to explain, so I think that first line can come in a substitute for trying to form a longer sense of what the book is about.
