I listened to the audiobook, as I’ve listened to over a hundred audiobooks before this one. The author should have gotten a professional reader to read and record the book. The author’s voice inflection and modulation were terribly annoying. I even changed the playback speed several times in an attempt to improve the experience. No luck. Also, I was disgusted that in a book about the Oregon Trail the author would inject his own anti-Christian beliefs. After twenty-five chapters of that torture, I’d had enough I’d never recommend this audiobook!
