Some of these books have FREE podcast audiobooks on iTunes U. Check out the ones from USF (University of Southern Florida). This might make it easier to get the reading done since you can (assuming that you can) listen and pay attention on your school bus. I would recommend that you also read along in your book. If you are not good at paying attention to a person telling a story DO NOT CONSIDER THIS OPTION, read your book instead.
