So that was only two days after publication. He seemed fairly engrossed for the one stop he travelled reading it. Personally I cannot see the appeal to adults (give me Philip Pullman in this genre anyday), but I must be in the minority here. But good luck & well done to JK Rowling who's earning about a million pounds a hour out of the latest book. I'm sure this guy will be the first of many that I'll see reading this on the London Underground.
