What’s the catch?

There’s no catch, but there is an earnest request. After you’ve listened to your audiobook, we ask that you leave the author a review. Reviews are really important to authors. So, for all their many months of hard work, we ask that you spare just a few moments of your time to leave a review. Within your review, you must state that you received your audiobook for free and that your review is voluntary. For example: I was given a free review copy at my request and have voluntarily left this review.
