One of the publishers I narrate for, Hedon Press, has run afoul of Amazon / Audible. I just learned that 11 audiobooks I narrated are being taken down. (Yes, it's rotten.) I'm in talks with Audible, more on that as I know more.
The audiobooks are for the moment still for sale through Apple Books. If you want them, get them FAST before they're gone for good.
I cannot in good faith recommend that anyone sign a contract through ACX to be paid in whole or in part in royalties because ACX/Audible is prepared to take down audiobooks without warning to narrators and leave us no recourse to be paid for our work.
I'm horrified that this is the outcome of my case. Please avoid this situation for yourselves.
