The book is from the late 70s-early 80s. A woman gets divorced, then retreats to Cape Cod in the winter. She lives in a house on the beach, learns to be alone and independent. I think she has a dog. Eventually goes back to society. Nonfiction (I think).
Are you sure it was Cape Cod? This sounds like A new Kind of Country by Dorothy Gilman. She spent the winter in a cottage on the beach in Nova Scotia after her sons left for college. She was divorced. It was published in 1978.
That looks good, but it’s not the book. Thanks for the suggestion. Cathy has solved it 🙂
An Unknown Woman – Alice Koller
One of my all time favorite books
I believe that’s it! Thank you!
