The Night of the Scorpion is the second book in the Pentagram series by British author Anthony Horowitz. It was published and released in the United Kingdom on 4 January 1985 by Patrick Hardy Books and 1 November 1988 in the United States by Putnam Pub Group. Initially envisioned as a pentalogy, only the first four books in the series were ever written and published. Between 2005 and 2012, Horowitz released an updated and re-imagined version of each of the first four books in the series, along with a fifth book to conclude the series. This series was marketed instead as The Power of Five (re-titled as The Gatekeepers in the US). The book which The Night of the Scorpion forms the basis of was released in 2006 under the name Evil Star. Source: Wikipedia (en)
