Descriptions of the Pacific Northwest are accurate and beautiful. The rhythm of the book captures the frustration of its characters and makes it part of your life. I felt I was on the sea paddling for seemingly forever. What kind of characters are required to make a superhuman effort? What kind of relationships are developed by disparate humans when pitted against great odds? Doig helps to answer these questions. This is a MUST READER for understanding the Pacific Northwest.
Output:
Positive
