I just finished reading "Harriet Beamer Takes the Bus by Joyce Magnin. The title character is forced by her son and daughter-in-law to move in with them after an older adult fall. But Harriet manages to turn this move across country into an adventure.
I'm wondering about other novels in this genre. (see!) I can think of Best Exotic Marigold Hotel by Deborah Moggach. This was also a great movie. And one of my favorites about a spunky that's-how-I-want-to-be-when-I-grow-up woman is Walking Across Egypt by Clyde Edgerton.
Does anyone have others to add to this list?
