..... being charitable I'd like to say this book has some good ideas.
But really it's a mess. Sometimes the 'dual author' approach produces excellent literature - look no further than 'Good Omens'. However when it goes bad - and make no mistakes, this book IS bad - it's like being shouted at by two different people, neither of whom has anything of interest to say. How a writer of Gaiman's acumen and ability came to add his name is beyond me. Great shame.
