Opus Dei: An Objective Look Behind the Myths and Reality of the Most Controversial Force in the Catholic Church is a book written by American journalist John Allen, Jr. about the Prelature of the Holy Cross and Opus Dei, published in 2005. While the book received mixed reviews, there were more positive reviews than negative. Two journalists referred to it as "widely considered as the definitive book on Opus Dei." On the other hand, some said Allen "applied a daub of whitewash." Agenzia Giornalistica Italiana (AGI), a major Italian news agency, described his work as having an "empirical approach" and that his book is of "great historical and journalistic interest."
