If you've read Artemis Fowl books 1 and 2, then you'll recognise the format, but that's no bad thing. Why change a winning formula? This book has all the elements which made the first two books so good, without being predictable. As before, the book combines a little magic with a lot of very hi-tech wizardry. This story features a super computer, cryogenic treatment, a sound bomb, an unbreakable code, and lots more techno trickery. Fans will be pleased to hear that all the best characters are back; Butler, Juliet, wise-cracking Foaly, short-tempered Commander Root, Mulch Diggums, and of course, our heroes, Holly and Artemis. In short, the Eternity Code is a very good book, with an exciting plot full of interesting invention. The complex nature of the technology means you can never be sure of what to expect. Artemis is a wonderful hero - he's not goody-goody by any means, but he's beginning to show twitchings of conscience and vulnerability which make him irrestistably likeable. Not to mention that he's very intelligent, not interested in sport, drinks Earl Grey tea, is yet still cool! That's probably the greatest achievement of all!
