Audible is very reasonable, if you signup for one of their plans. As for books, really anything that you find interesting will work. I personally love Harry Potter, C.S. Lewis' Space Trilogy, The Hitchhiker's Guide to the Galaxy Trilogy, LOTR, Dracula, etc.
This is my second time around with weight loss. Originally lost from 220 down to 155. Learn from my mistakes and don't relapse! LOL
