Started as a radio series in 1978, The Hitchhikers Guide To The Galaxy has grown into a genuine phenomenon - encompassing five bestselling novels, a BAFTA-winning TV series, albums, stage productions, a computer game, comics, and a feature film. Now comes the sixth novel in the ever-more increasingly inaccurately named trilogy, written by bestselling children's writer, Eoin Colfer (Douglas Adams died in 2001). While die-hard fans are familiar with every detail of every format, and every slight discrepancy between them, the merely curious might appreciate this introduction to the absurdities of The Hitchhikers Guide To The Galaxy's universe. Yet this guide to the Guide also contains plenty of extra material that may be unknown.
