audiobook shelf or plex with audiobook metadata {audnexus](https://github.com/djdembeck/Audnexus.bundle) or jellyfin with audiobooks. i personally use plex since thats what i use and have not had an issue with any books. but i also have audiobookshelf fully setup and working just that it needs a vpn to route into my instance so plex is simpler but both options work perfectly.
