I really didn't like the sample of this book. Overly simplistic writing with a few big words thrown in to make it seem more sophisticated (pardon the pun) and the last straw was the line where a guide dog was described as "more trouble than he was worth". I find this hurtful, having several visually impaired friends and being fully aware of the cost and effort of training and owning a guide dog but also how rewarding this is for the person and charity.
