If you are a big time reader and like eBooks (like me), then you need to know about Smashwords. "Motor City Shakedown" was my first FREE download from there. The eBooks from Smashwords are DRM-free and can be downloaded in just about in any format.
If you like Grisham, you will probably like this book:

I also just finished the second book in the series. This one was not free, but it was just $2.99 (the author will get 70-80% of that unlike the 10-15% with traditional publishers).
