ChristianAudio.com has a free audio book download each month.
In the past few months I’ve downloaded The Imitation of Christ by Thomas A. Kempis and Orthodoxy by G. K. Chesterton. So, as you can see, they aren’t fluffy books.
This month they are offering All of Grace by C. H. Spurgeon.
Redeem your commute. Listen to good books! 🙂
