I love to read Louis L'Amour's books. I have read them all, starting 30 years ago and they are an easy read in hotel rooms, on buses, planes, or just to relax before bedtime. When I get a good book, I don't want to put it down, so I like to be able to read the whole thing in 2 or 3 hours. I don't really go for long novels that I have to read over several days, although L'Amour had a few novels that were worth it, but I ended up reading them straight through instead of sleeping.
Possibly the best book I have ever read was Shepherd of the Hills. Even though it was written about the area where I live and it was the basis of Branson, Missouri exploding as a tourist area, I had not read it until a few years ago. It was written about 1907 and it has just as much ethical and moral value today as it did back then. If you want something to give you a lift and make you think, it is a must read.
Isomade, I agree, Elmer Keaton's, The Time it Never Rained, is a great book. It was a really hard read for me, because it hit too close to home, but a great book, never the less.
