Book and film reviews An amazon.com computer glitch in 2004 revealed the names of many authors who had written pseudonymous reviews of their books. John Rechy, who wrote the best-selling novel City of Night (1963), was among the authors unmasked in this way, and was shown to have written numerous five-star reviews of his own work.
