Rankin has been compared to Pratchett and Adams.. this is unfair. Rankin is Rankin in the same way as Pratchett is Pratchett, they shouldn't be compared because although both are brilliant they are brilliant in quite astoundingly different ways. All of Rankin's books have a different feel to them, and if you didn't know, you could swear that some were written by different authors.. but despite that there are always those rankin touches.. the Running Gag.. oh how we love the running gag.. not just running through chapters but running through every book. Armageddon the musical is a start of a trilogy of books all concerned with... yup, the end of the world. The good guys include Rex Mundi (King of the world, although only by name) Elvis Aron (or Aaron, no one is really sure) Presley.. Barry the loqacious sprout, what better could you ask for. The plot twists and weaves and is quite complex but it all makes sense and it all adds up to the really and tottaly unexpected trick ending (no, don't skip forward, you'll spoil it) I have heard it said that it's not as Rankin-esque as "The book of Ultimate Truths" but that's one of Rankin's Strengths, There's always something new. Buy this.. buy all his others too. You'll be happy.
