Artemis Fowl: The Time Paradox

Probably the most interesting result of the time travel is that we see how Artemis was before meeting Holly and how he is now. We, as the readers, are not the only ones who see this. Artemis himself is surprised to notice how much he has changed in the last few years.
This book, like the last one, is lighter, although in a less childish way. One of the side effects of the time travel is that Holly is reversed to a younger self, a younger self that is the fairies’ version of a teenager. It is funny to see how she knows the reason behind her unusual feelings and thoughts but can’t do anything about it.
Better than the last one, but still not as good as the first four.
