The Bar None Ranch(1987)
(The second book in the Duncan and Mallory series)
A novel by Robert Asprin and Mel White
Asprin's story and dialogue are witty enough to stand by themselves....Mel White's hilariously expressive drawings at least double the fun (Gene DeWeese). This series is now something of a cult collector's item.
