Slow Waltz in Cedar Bend is a novel by Robert James Waller. It was the third highest seller in the US in 1993, after Waller's Bridges of Madison County, to which this book was his followup, and John Grisham's The Client. Over two million copies were in print by the end of 1993. Waller was himself an economics professor at Northern Iowa University and so writes about his experiences about the main protagonist.
