Through the narratives, the author weaves some history, philosophy, nature studies and a lot of fond memories with a great deal of love for his Dad. Yes, the book is largely about eels, but much more. His connection to nature comes through as well as his concerns for the environment. So when you read the book, you learn much more than expected. Patrick Svensen is the type of person we need more of. He’s thoughtful compassionate and caring. The book is well worth reading.
