Simply put, the audio abridged version is definitely good for one of your shorter trips. 2hrs each way total of 4. The book was comprised of a few unsuspecting twists which made it very interesting. The message was a good one. Inspirational.
I'm a big fan of E. Lynn already so I already knew this was going to be good. It kept me on the edge of my seat the whole time! It helps if you've read all the books because they all tie in together. I'm a little bummed out since I heard this was his last book. I highly recommend it.
