this guy had his wife write it. He says he's going to teach her how to use a computer. He's not. And he doesn't even mention that.
Bad review

I was rather disappointed with this book that promised to offer a true account of the real life adventure of one courageous pilot in the Spanish Civil War. While written very well and quite interesting, it does seem at times like an essay which reads more like history than fiction. The author apparently decided after finishing the manuscript (which includes photographs from his personal collection) about half way through writing it, that he would create a story around it.
Good Review

the quality of the product is great but be aware that if your dog likes getting up on them you will have to buy a separate training collar.
