Parnassus on Wheels, by Christopher Morley

This short novel is about a spinster women (of about forty) who buys into a travelling book wagon run by a bookloving single man of a similar age. Of course it turns into a romance. Parnassus on Wheels was published in 1917, so it is over a hundred years old, and the century does not sit on it well. The root problem is that the travelling Parnassus is based upon the idea that all rural folks love books, and are eager to buy and read them. I doubt that was true in 1917, and following the advent of radio, television, gaming, internet, streaming services, etc. etc., it's very clear today that rural folks young and old are interested in doing almost anything other than reading. And the writers admired by Christopher Morley's characters in 1917 haven't withstood the test of time either. But the story itself has some attractions, and one doesn't need to buy in to the story's applicability to enjoy a few quick hours of pleasant silliness. There is a sequel, with the appealing title The Haunted Bookshop, which takes place after the couple settle into running a bookshop, but it, alas, contains nothing supernatural.
