Query: I am having trouble getting through chapter 1

I just started this book last night and haven't even made it through the first chapter. I had to check the reviews here to see why I'd even purchased the book in the first place (I buy a lot based on recommendations). I was shocked to see all the positive ratings.The book is loaded with grammar and spelling errors. If this doesn't bother you then you might find the book enjoyable. I'm not an English major, or one to correct anyone's grammar, but I expect a book to be written much better than this. A good proofreader would have easily discovered these mistakes.I don't know if I'll finish the book at this point. Very disappointing.
