The “reader reviews” on Amazon.com have become a genre unto themselves, with some amateur critics posting thousands of the things. But authors tend to hate the self-styled literary judges, who think nothing of savaging an author’s character as well as her work, and this month, Anne Rice had had enough. The popular author has seen her two latest books trashed extensively on Amazon, and in response, has posted a 1,200-word defense of her latest effort, and given the critics a taste of their own medicine, accusing them of “[using] the site as if it were a public urinal to publish falsehood and lies.”
