While this isn't my cup of tea, I came across a freebie (thanks to Mary Burkey over at
The Booklist Reader) and thought you might be interested. You can get all twenty of the audiobooks in "The Bulford Series" for free over at
their website. It's written and intended for younger audiences (middle- to high-school) and is very topical for younger readers.
Enjoy!
