ETA: Sorry, this offer is over now. You can still get a free book, but it won't be mine.
For a limited time (and I will confess no one has told me how limited) you can get an electronic copy of Disenchanted for free from a new service called Runaway Goodness. You sign up for notifications of special deals on eBooks and you get the first book free. To get Disenchanted, choose Christian as your preferred genre.
