This is another of Anthony Horowitz's series of books, so far we have had:
Ravens Gate
Nightrise
Evil Star
Necropolis
And there is one more still to come, this series is about 5 children who must band together and save humanity from the old ones. It is set on earth but there is quite a lot of fantasy involved.
