I'm looking for easy-to-listen-to fiction audiobooks. Something I can tune in while doing other stuff without getting distracted.
I find some authors have styles that are a bit more sophisticated than others. The more thought-provoking, the more difficult I find to enjoy an audiobook while doing something else. I catch myself stopping whatever I'm doing to pay attention to the book, which is not what I want.
So for example I've found The Witcher books very easy to listen to, it wouldn't matter if I missed a few seconds and I never found myself stopping to ponder about the text itself. The narrator was great too. Also bonus points as it was a long saga of books.
In contrast I would never want to listen to a Terry Pratchett book while doing something else. He's probably my favourite English author but I find he's too much of a genius, and my poor brain wouldn't be able to digest it all if I'm not giving it my attention 100%.
I recently listened to Daisy Jones and the Six and the audiobook was incredible. The book was written as a series of interviews, which worked great as an audiobook. There were definitely times I got a bit distracted but it didn't impede my understanding too much. It does take a bit to absorb all the characters, so you'd probably want to listen uninterrupted for the first ~hour.
Killers of a Certain Age is another good one. Written about mature women assassins. It's a fun thriller and an easy listen.
Final rec is any of Ken Follett's Kingsbridge series as read by John Lee. They're long as hell, but straightforwardly told. There's something I just love about how John read them, too.
