The Exorcist by William Peter Blatty has already taken a strong place among the world's bestsellers. It went through many reprints not only in the USA, but also in other countries of the world and was translated into dozens of languages. No wonder the author of a book review in the New York Times Book Review wrote that The Exorcist “is as superior to all works in its genre as Einstein’s equation is to an ordinary column of numbers.” The novel Legion continues the theme begun in The Exorcist the devil." There are the same characters, the same sharp, fascinating plot and the same deep problems as in the previous novel.
