As other reviewers have said, this book is mainly about the snail in culture and history rather than a biology book. I own "Leopard" in this series, which was similar and marketed as such, so I'm not sure if people didn't read up on the series or if this book was marketed differently. In any case, I went in expecting that, as I find animals in culture an interesting topic.
The book was decent. I learnt some new interesting facts, but I definitely got the sense there wasn't much to work off here, or at least that the author struggled to synthesise what he had. Some sections felt repetitive, as if stalling for time or trying to fill a word count. The chapters could also have been organised better. Still, it's a neat little book snail lovers should enjoy.
