The Amber Spyglass, the last book of Philip Pullman's His Dark Materialstrilogy has just missed being the first children's book ever to benominated for the Booker Prize. The three books -- Northern Lights (or TheGolden Compass in the US), The Subtle Knife and Spyglass --have receivedlittle global attention compared to the monster success of the Harry Potterbooks and this is a shame. In fact, well OK, let me put my neck on the lineand say it: His Dark Materials, I believe, is quite simply one of thegreatest literary feats of the 20th century.
