I purchased the following books for my Kindle last week. One of them was free so technically that one doesn't count.
Blood is Red by Scott Sigler
For Whom the Minivan Rolls by Jeffrey Cohen
Witness to Death by Dave White
Plan B: A Nick Heller Story by Joseph Finder (FREE)
Here Comes Mr. Trouble: The Trouble Family Chronicles by Brett Battles
Vanished by Joseph Finder (I own this book in paperback and hardback, too)
Julius Katz and Archie by David Zeltserman
Hmmm. I've got no explanation for this. None.
