Query: quite a disappointment

I am quite disappointed by this book. The author lacks the skills and judgement on how to handle serious issues such as homophobia, racism and environmentalism in a remotely ingenious way. The characters are dull and superficial, serving no greater purposes than mindless plot devices. The pace is slow and the dialogues seem to go in circles. Worst of all, the editor (if there was one) could not even spot the most obvious grammatical and spelling mistakes. You bet I won't buy another book by Mr. Keegan.
