Even as he purred, Artemis winced at how ludicrous the situation had become. It was a typical Fowlesque melodrama. Two parties hunting for a lemur on the highest power lines in Ireland.When Angeline Fowl falls deathly ill with a magical disease, Artemis enlists N01's help, and together with Holly, travel back in time eight years to save a lemur from becoming extinct -- at the hands of his own, 10-year-old self. His younger self proves to be one of the most formidable adversaries the pair have ever faced.Of all of the Artemis Fowl books, this one is probably my favorite. Pitting the younger, more dastardly Artemis against his own older, more mature and selfless Artemis provides the opportunity for all kinds of clever jabs and one-liners, as well as accentuate just how far Artemis has come over the course of the series. And, of course, I'm always a sucker for time travel stories. Though this one definitely took a different direction, creating an actual paradox, which made for some interesting, mind-twisting situations, including a few surprisingly interesting lines by the younger Artemis at the very end.A few things, though, that I wasn't too fond of...- A kiss. An unnecessary and awkward action that completely changes the dynamics that have been set up over the course of the series.- The twins. They don't really act like two-year-olds, but are too irritating for their supposed super-genius to really be impressive.- A few inconsistencies. If Mulch wasn't mind-wiped, wouldn't he have known Artemis in the first book of the series? If Opal really escaped LEP in the present-time, she wouldn't be in the past to complete all her evil deeds from the previous books. Also, when he confronts the Extinctionists, the author describes Artemis's blue eyes -- he would have had one hazel!Heads up: More cartoon-like violence and fart jokesOverall: A fun, exciting adventure back in time with our favorite teenage criminal mastermind-turned-teenage not-so-criminal mastermind.
