Elevenlabs is a lot closer to compelling audiobook narration (needs a better way to deal with multiple characters in a story without manual use of multiple voices): https://pub-a24da573c61f4b2d905bdebb2d0ecf88.r2.dev/ElevenLa... (an H.G.Wells example I just asked it to read).
I was going to mention ElevenLabs, too. Their samples are very impressive in how the intonation and word stress are varied based on the text’s meaning. Their pricing is a bit high for personal use, though.

Yeah, sadly it'd cost about $100 to get a book per month... Not quite competitive with Audible yet, but give it a year perhaps, or a few iterations of the open source models... (fixed the link)
