Since we had 36 hours to kill each way to Montana we listened to a few this past trip. None hunting related but pretty good non the less. One was "The Things They Carried" it was a interesting collection of short story from Vietnam soldiers. Another was "Deception Point" A little slow in the start but it all comes together in the end. The third was "Pirate Hunters" Really good book about a few divers quest to find the Golden Fleece pirate ship. They might not be what your looking for but they are pretty good audio books.
