The Power of Five
series of five fantasy and suspense novels by Anthony Horowitz

The Power of Five (known as The Gatekeepers in the US) is a series of five fantasy and suspense novels, written by English author Anthony Horowitz. Published between 2005 and 2012, it is an updated re-imagining of Horowitz's Pentagram series, which the author had left unfinished in the 1980s after he only wrote four of the five planned books in the series.
The novels deal heavily in the occult and examples of things such as human sacrifice and blood rituals are major plot elements, such as in the first book, where Matthew Freeman is hunted by a cult who want to conduct a blood sacrifice on him to blast open a portal using a combination of nuclear physics and black magic, to unlock another dimension which is holding a group of ancient evil demons captive.
The series is published in the United Kingdom by Walker Books Ltd and in the United States by Scholastic Press.
Plot overview
The series focuses on five children: Matthew Freeman, Pedro, Scott Tyler, Jamie Tyler, and Scarlett Adams, a group of five modern day teenagers with some sort of power who are expected to defeat the Old Ones and save humanity.

This brief starts where responsible research should: with the source description of “The Power of Five” as series of five fantasy and suspense novels by Anthony Horowitz. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as series of five fantasy and suspense novels by Anthony Horowitz. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 3, 2026. The linked authority identifier is Q2156439. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2005, 2012, 2006 and 2007.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
