"Clara Callan" is about two sisters- Clara and Nora. They were born in a small town in Canada. Nora moved to New York and became a soap-opera star, while Clara stayed in the small town. The focus of the book is the bond between sisters.
A librarian that I knew said that "Clara Callan" was her favourite all-time book. It didn't click with me.
In "October", James Hillyer traveled from Canada to England to visit his daughter, Susan, who had been diagnosed with cancer. While there, he encountered Gabriel Fontaine, a man he knew from one summer when the two men were teenagers in Perce, Quebec. Gabriel was dying of cancer and asked James to accompany him to Switzerland where he had arranged to be euthanized. These events caused James to recollect that summer sixty years in the past, and to ruminate on life and relationships and death. I liked this book better than "Clara Callan" and found it an enjoyable read.
