I was wondering if there is an easier way to search kindle unlimited book that have Whisper sync/audio included. Right I just look and hope I find one!!!
here's what i do
1) on computer, go to amazon.com/ku
2) click on "browse the catalog"
3) click on "eBooks with Audible Narration" on the left side
