I know Dennis and consider him a friend. Reading his book is like having several meeting with him and listening to his side of the conversation. If I had named his book, it would be “Principles” instead of “Ethics” because throughout the reading he shows a consistent and principled approach to dealing with conflicts and problems inherent in being a professional surveyor.
Depending on your frame of mind when reading, it could be hard to keep reading or hard to put down. That is okay since each chapter stands on its own very well. (
