We have a long car trip (12 hours of driving one way) coming up and enjoy listening to audio books during trips.
We've enjoyed The Hobbit, Narnia, Charlie and the Chocolate Factory, Hotel for Dogs, Because of Winn-Dixie, Mouse and the Motorcycle, and Ralph S Mouse, and some of us have enjoyed Cat of Bubastes and Black Beauty. They've listened to lots of Librivox books, I can't even name them all.
Any suggestions? My kiddos are 6, 7, and almost-9. They tend to be easily scared. I'm not opposed to purchasing something really good and classic but Librivox is good too.
