There were two books that I completed in 2021 on Audible that I couldn't find here. One was "The Great Poets: Robert Burns" by Robert Burns, narrated by Forbes Masson. The other was "Down Range" by Taylor Moore, narrated by Jeremy Arthur. I also had two different versions of "The Red Badge of Courage", written by Stephen Crane. One was narrated by Anthony Heald, the other was narrated by Michael Scott. (Not the Nicholas Flamel book series author I assume). According to my Audible records, I completed the Heald version.
Also, when choosing the book images, I try to use the pic from my audible, or in the case of Thrones or Potter, the cover I'm most familiar with.
