I Recommend... Artemis Fowl
Artemis Fowl is a novel series written by Eion Colfer focusing on the criminal antics of teenage mastermind Artemis Fowl. When his father is lost at sea he comes to the only rational conclusion, he should kidnap a fairy to pay for his fathers life. In further story's there is time travel, billionaire terrorists and the complete destruction of the world we know it.
The writing is humorous and exciting. The idea's are creative and fresh and the visuals are interesting and intriguing.
A must read. Though not as perfect as Harry Potter but definitely one of the best … young adult? teenage? child? novel series out there.
