Yes it is out of print, but look for it in used bookstores. In fact look for the whole series. These are very good light reading. The characters are good and the stories keep you interested. I no longer fish, but I enjoy reading about these characters who do love fishing, cooking, nude sunbathing, and other island type lifestyles. I don't think a lifestyle of this type would be for everyone, and I know it's not for me, I enjoy air conditioning, television, and the middle of the country, although a visit to Martha's Vineyard isn't beyond hope.
Find all of the out of print ones if you can, visit the library and find those you can and then plunge in and enjoy.
