I received a phone call from a customer at the airport waiting to board her plane who needed to access her downloaded books before departing. She explained she couldn't find her Kindle books on her Kindle Fire carousel, so I started to troubleshoot what could be wrong. After a few questions were answered we realized that since these were audiobooks she needed to access them using the Overdrive app. I helped her find the books by using the three line tap menu and selecting "Bookshelf." I asked her to touch one of the titles and I waited in anticipation. "Does it play?" I asked. She said elatedly, "Yes!" So she got her books before the plane departed. Whew.
