Western author Louis L’Amour, wrote a really fine book with two children as the protagonists. “Down the Long Hills,” published in 1968, won a Golden Spur award and I don’t know how his publisher marketed this book, but the cover design is more classic western than middle-grade reader. I stumbled on it in the 1980s and it’s one of those classics I like to re-read. I sometimes wonder about these genre labels focused on age, how much they help and how much they hinder those of us looking for the next good read.
