I definitely enjoyed the read, but I did have to work hard on the many accents that are represented in it. There's American, Scots, Dutch, Portuguese and others. Given that I'm not keen on reading dialects, multiple dialects worried me a bit. But it actually worked out ok and I don't think it took anything away from my enjoyment of the book. The only other thing that I would say is that the character of Harvey's dad didn't seem believable to me. He just doesn't seem like the kind of guy who would raise the kind of person that Harvey was at the beginning of the story.
Anyway I would definitely recommend it if you are after a quick read that's just a bit of fun.
