The Unlikely Pilgrimage of Harold Fry and The Love Song of Miss Queenie Hennessy

I'm of two minds about this book. Partly, I felt it was sentimental fluff and the main characters were stereotypes of an older couple whose marriage had gone bad. Partly, I wanted to find out what happened, and I did like the characters that Harold meets along the way in his journey from the south of England to the north. I liked the simple, unadorned prose style of the story, and I appreciated that it was told from both sides of the unhappy couple. The book grew on me as I read, but then I was really irritated by the climax of the story and the resolution of the problem. Apparently there's a companion novel about Queenie Hennessy, the woman Harold walks the length of England to say goodbye to–but I won't be reading it.
