Necropolis Anthony Horowitz Published by Walker Books ISBN 978 1 84428 622 5 The fourth novel in The Power of Five series, Necropolis continues the story of five teenagers with the power to save humanity from The Old Ones. The Old Ones are an ancient evil that is threatening to destroy civilisation and make chaos of the world. The five teens are The Gatekeepers, and they are the only force that can stop The Old Ones from destroying mankind. The first three books in Anthony Horowitz's series have been phenomenally successful - but can he keep up the adrenaline rush? Horowitz is a clever writer who keeps his stories rocketing along with all engines fired, giving the reader no time to breathe. Necropolis has all the necessary flashes and bangs to get you through to a final sentence that promises more of the same. On a school trip to an old church, protagonist Scarlett Adams finds herself transported to a monastery in central Europe, where she is told The Old Ones need her. On the other side of the world, Matt Freeman, the first Gatekeeper, realises Scarlett is the important fifth Gatekeeper. Matt decides to go to London to tell her who she really is. But Scarlett is suddenly whisked off to Hong Kong, where her father works. Hong Kong turns out to be a very strange place, with a thick mist hanging in the streets and people walking around like zombies. Scarlett is about to find out that The Old Ones have turned Hong Kong into a city of the dead. To Young Post readers, the final section of the book will have its weaknesses. A few street names here, a few place names there and one very ill-judged paragraph don't capture the city. But if you can ignore this and get on the roller-coaster, you will enjoy ride.
