Eoin Colfer was born in Wexford, Ireland. He attained worldwide recognition in 2001, when the first Artemis Fowl book was published and became a New York Times Best Seller, as did some sequels. Among his other popular works are Half Moon Investigations, The Wish List, The Supernaturalist, and a series of Eoin Colfer's Legends. In January 2008, Colfer published a book titled Airman, another best-seller. To date more than half of his books have reached the New York Times list at least once. Colfer currently resides in Wexford, Ireland with his wife, Jackie, and two children, Séan and Finn.
The first five novels in the Hitchhiker's "trilogy" were written by Douglas Adams. Adams' widow, Jane Belson, and the literary agency that manages Adams' estate asked Colfer to write another book, as Adams had intended to add to the series, agreeing that the end to the fifth book was "very bleak". Already a fan of the series, Colfer called the opportunity "like suddenly being offered the superpower of your choice ... For years I have been finishing this incredible story in my head and now I have the opportunity to do it in the real world ... It is a gift from the gods. So, thank you Thor and Odin."
