Wow, the book isn't even out and I get two five star reviews warning people not to buy it. That's a first. It's possible that some readers may not know that Puffin is a childrens' publisher, and they might miss the cover which clearly has a young teen depicted. However, I am can assure you that very many adult readers have enjoyed the first book and will not doubt enjoy this one. In the same way that other, rather more successful, kids' books reach a crossover audience, e.g. - off the top of my head - Harry Potter. I do find it depressing that people draw boundaries like this. One of the best books I have read recently is Private Peaceful. So, a little less prejudice and a more open mind might just deliver new pleasures, chaps.
