We stayed in the town of Anascaul a few years ago and enjoyed a pint or two at the South Pole Inn. Got Michael Smith's original book and enjoyed it very much. Straightforward, and informative writing.
Based on 10 additional years of opportunity to learn more - particularly from sources that emerged after publishing the first book - this book provides a physically shorter, but more comprehensive narrative. A key term is 'illustrated' as the many photos now included add depth and scope to the story.
If you enjoyed the original, this will also be satisfying. If you are unfamiliar, this book is a great starting point (and you may well learn more than you ever thought asking about).
