On a recent trip with my family, I chose a few audio books that I thought would appeal, not only to me, but also to my husband and my mother-in-law (who really likes westerns.) I really enjoyed listening to The Misadventures of Maude March, Or Trouble Rides a Fast Horse, a historical novel by Audrey Couloumbis (who also wrote Getting Near to Baby, which I loved reading a few years ago!)
Interestingly, we listened to this story about two twice-orphaned sisters who started an adventure on horseback from Cedar Rapids, Iowa to Missouri, as we ourselves were traveling from Iowa to Missouri, so that was kind of a cool coincidence. The story is suspenseful because Maude, the older sister of the narrating character, Sallie, goes from being a prim and proper young lady who is always correcting her sister's grammar and criticizing her for reading dime adventure novels to being wanted for horse-thieving and bank robbery...
Since we are done with our trip, and I only listen to books on CD in my car, I am still waiting to see how it turns out...but I also just ordered a sequel that should arrive at the library soon. I highly recommend this title to readers of all ages (either the print book or the CD.)
