What is a J.D. Robb Reading Challenge?

[Colleen]

GREAT QUESTION!

We know that a lot of you will be reading at your own pace, and - in addition to keeping up with the on-going re-read - may want to set some other reading goals for yourself, so we created a few different kinds of challenges for you. The instructions for each challenge will be in the first comment. We hope you have some fun with these! Enjoy!

I have never read these books, but have been meaning to for years. So this won't be a re-read.
