The fourth Artemis Fowl book from Eoin Colfer is another brilliantly written story that is original and enjoyable. This time, the fairy people realise they need Artemis Fowl again after an old friend (the clue is in the title) returns to get her revenge. However there is one teensy problem ... ... Artemis remembers nothing about fairies. His mind wiped at the end of the book 3, he is rendered far less useless than he has ever been. With Holly accused of murder, and an ally they will definitely need in jail, the race is on, with very little time to save the fairy and human world - and with everyone against them, it is going to be incredibly difficult. Despite a few shaky points where you consider the possibility of plot holes and inconsistencies with the other books, this book is highly enjoyable. Eoin Colfer never resorts to a typical formula, each book taking on a new form - and this is no exception. Instead of Artemis hatching a plan (books 1 and 3) or him making a deal with the fairies for them to both complete missions (book 2) they are now solely depending on him, with him not remembering anything about what the last few books have contained. One of the brilliant things about the books is the incredible plans that Artemis creates to get out of impossibly scenarios. They never fail to amuse and amaze, and always extend the credibility of his character - a fair task when he is 13 and a criminal genius. One problem with Eoin Colfer's writing is his way of flipping back between times so much (ie telling the same scenario through different eyes). The fact that he does it is not the problem, it is more the order in which he does them that is annoying - a fact that may be visible to people reading the book. Well, writing this took 10 minutes. I think that's substantial. I look forward to the next book - there'd BETTER be one!
