Author Lee Child and his Jack Reacher series are great! He needs to write and publish faster!! I am always waiting for the next one. Michael Connelly's series with Harry Bosch are also great. The Janet Evanowich series with Stephanie Plum are hilarious! You will love Lulu! David Baldacci also has good ones. I really like CJ Box--Joe Picket series. I've listened to all of his on CD, but now his new ones are all audible which I don't do---yet.
