I really liked the premise(s) of the book, however, and it should say something that I kept reading it regardless of the style. I need to see if there are other books in this particular corner of his universe, because there are lots of interesting open questions. I was disappointed that this book lacked the subtle subplot / moment of revelation his better books have. I think he relied too much on the broken English and in effect gave away too much of his hand early on.
Overall, probably worth reading thru, but I'd pick a better book, such as Use of Weapons, as an introduction to his writing.
