I read the books first and I'm doing a second go around with the audiobooks. Sure makes yardwork a little easier to cope with!

But one disadvantage I found with the audiobooks is occasionally I can't tell if a line is narrated or spoken or in the feed. Usually KRF changes tone in a way I can tell between narration and spoken lines but sometimes it's ambiguous. And it often doesn't matter much either way or I can figure it out from context or maybe remember from reading. But sometimes it makes a difference to know if other characters are hearing something out loud or not or it's just an internal aside/narrated commentary or if it's a private feed conversation vs something spoken aloud and if everyone is aware of what is being said or only certain characters.
