I came across this book through my mother who lives just a few valleys away from 'Hafod'. She spent a large part of her childhood growing up in a cottage just down the track, and has fond memories of many of the characters portrayed, and of the house in question.
I found the book easy to read, and extremely enjoyable. Maybe it does paint a rosier and more 'olde worlde' view of that part of Wales than is actually the case, but it didn't strike me as being pretentious, and speaks of the local community with such fondness that I think they must surely be proud to have been portrayed in such a way. As for the nicknames, having watched Ivor the Engine with Jones the Steam, I feel sure that these are real, if not names that are generally made known to people outside the local community.
Overall the book is full of the 'feel good factor', all-be-it tinged with a little true to life sorrow at times. A really good read.
