The Artemis Fowl series by Eoin Colfer
The Artemis Fowl series is notable for two reasons. Firstly, its inimitable blend of science fiction and fantasy is a true gem. An advanced race of mythical creatures lives underground, and humans drove them there after a long war. Secondly, its protagonist is one of the most well-developed characters in fiction. Artemis is a young criminal mastermind with a huge family fortune, and his journey from cold anti-hero to caring individual makes you feel an attachment to the eight-part saga. When the two parts meet, a thrilling and sometimes touching adventure awaits.
