HIs Dark Materials - get it, read it. I'll be suprised if you don't like and can't put it down. I read it over Christmas last year and seriously could not put the books down. As soon as I had finished one it was on to the next. The trilogy is incredibly vast - morals, theology, corruption, plots twists within plot twists, cosmology, physics, parallel worlds and one girl's destiny. I read it after finsishing all the Harry Potter books, but found these three to be in a totally different league. I don't want to give anything away but I highly suggest reading these.
