I signed up for the new Kindle Unlimited program last night (free for 30 days) because I was particularly intrigued that several of the titles also came with narration (i.e. audible audio books). I'm mostly interested in these narration titles because I read kindle books on my iphone5, so I don't like to read on my iphone after dark to minimize the blue light affecting my sleep patterns.
I searched my tail off and eventually found the proper search filters so I could just download books that have narration, and I wanted to share the link with you.
This link also has the results sorted by average customer review.
