Project Hail Mary is my #1 fav audiobook, hands down. Just don't look up anything about it beforehand, because spoilers would really ruin it. All you need to know its about a scientist on a spaceship who has a very important mission.

Try the Expanse series. It's long and very well done, but you can tune in and out and still get the story.

I set a goal for myself to get through as many of Stephen King's books as I can before the end of the year. To date, I've gone through over half of the Dark Tower series, The Shining, Dr. Sleep, It, Later, Under The Dome, Bag of Bones, Desperation, If It Bleeds, and I'm working on The Stand right now. Most of them are quite long, 15 - 50ish hours.

If you're not into horror, I still highly recommend The Dark Tower series. The recordings for the first 5 books are over 100 hours. They unfortunately had to change narrators in the 5th book, as the original sadly passed away. He did an amazing job at bringing the characters to life.

If It Bleeds is a short story collection, but it contains a sequel to King's The Outsider, followed by Holly, which just came out last month.

Lord of the Rings read by Andy Serkis

Any of Naomi Novik's books, particularly the Deadly Education series

The first two Hyperion books. (I've only read the first one but will read the second soon)

Those will get you started if you haven't read them already.

Pretty much all major books are published as audiobooks as well. Even ones that have computer code written in them, which is not something that you'd ever expect to have read out loud.

It used to be that books would be "narrated for the blind" where not a lot of attention would be put into the audio. Nowadays, there tends to be a lot more effort put into them. I suppose that's because they don't need to be packaged as 12 to 20 cassette tapes or CDs any longer.

There's the added element that a narrator can ruin or improve things. The Making of the Atomic Bomb by Richard Rhodes is a wonderful book, but the narrator displays an unprofessionally slim knowledge of physics.

Then there's World War Z. I'm not sure that there's a better way to tell that story than the audio book. It's the exact interview style that the author intended.

Orson Scott Card really likes audio books, so the Ender's Game series is really good.

Reckoners Series - Written by Brandon Sanderson - read by MacLeod Andrews

In fact, I'd probably recommend any of his books/audiobooks. His stories are very gripping but also very easy to follow, in my opinion.

This one is more niche but it's among my favourite audiobooks for both great writing and a stellar vocal performance.

I highly recommend the Eisenhorn trilogy by Dan Abnett and performed by Toby Longsworth. Or if you want to dip your toes then try the first one Xenos.

It's set in the Warhammer 40K universe but you don't need to know much lore to get into it. The trilogy is a pretty good primer into 40K.

I really enjoyed Stephen Fry's Greek mythology audiobooks. He wrote three, basically a modern editorial of the mythology cleaned up a little bit and presented as a more linear sequence of events. He did the golden and silver ages, followed by the Trojan war.

I also really enjoyed Neil Gaiman's Norse Mythology, narrated by himself. They are all easy to follow, and entertaining. Neil Gaiman's book isn't particularly to ribald as far as mythology goes, and my kids loved listening to it in the car.

Edit: also from the young adult section, Abhorsen and Sabriel are on audible narrated by Tim Curry, who makes them a hoot. Don't recommend the other two as much. The books weren't as good and they aren't narrated by Tim Curry.

I can recommend "The Realm of the Elderlings" audiobooks. James Langton has a British accent and it's just wonderful to listen to. He does voices for other characters fairly well too. Great book series too.

Becky Chambers - The long way to a small, angry planet

Discworld is my go-to these days. Goes well with cross stitching

In contrast I would never want to listen to a Terry Pratchett book while doing something else

Ah well. Sarah J. Maas was also a fun experience. It's so bad it's good. I went with A court of thorns and roses but I hear her other series follow a similar vein. It's hard to miss the important details. Look for the Graphic Audio releases.

Off to be the wizard. By Scott Meyer. It is hilarious and fantastic. Very similar in style to the hitchhikers guide to the galaxy

There's a free series you can listen to on Podcast Addict by Nathan Lowell. The first book is called Quarter Share. (Then Half Share, Full Share, Double Share, Captains Share, and lastly, Owners Share).

It's Sci fi set in space about a guy moving up in ranks making money and working on a space ship. It's nothing too fantastic but it was still a good listen, read by the author who does a good job of it, and I did exactly what you're wanting while I listened. Loosely paid attention while doing other things and it was great for that.

Also, you can't beat free.

The ice wind dale Trilogy by R.A. Salvatore is a great series set in the forgotten realms of dungeons and dragons. There's even a free podcast audiobook of it on Spotify!

The Hundred-Year-Old Man Who Climbed Out the Window and Disappeared

This book did this for me. It was funny and totally casual.

IT by Stephen King was read incredibly by Steven Weber.

Stephen King got me into Audiobooks after being a bit hit-and-miss with them but I've been using them when I'm out walking and then read the book when I'm home and have time. It's been a great way to zoom through his back catalogue.

I really got into the foundation series by Isaac Asimov.

Jonathan Maberry, Joe Ledger series is a really good action, near future sci-fi, popcorn romp, style of fiction. It's like Saturday morning cartoons (just sit and listen) combined with some good writing.

A Night in the Lonesome October byRoger Zelazny. The version read by the author is better but harder to find these days.

This is also the perfect month to listen to it. It's the diary of Jack the Ripper's dog from October 1-31.

I used to work while listening to audiobooks so I have come across a lot of this.

It's not quite what you asked for but what I found was that in general, nonfiction memoirs were my favorite types of books to listen to as it would be ok if you get distracted and they were usually very interesting to me.

If I remember later I'll check my list of books I've read and try to find some good fiction too.

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.

Stephen Fry’s reading of Harry Potter is just the best.

On a JK Rowling note. Her Cormoran Strike series (starting with Cuckoo’s Calling) under a different pen name is actually pretty great. It’s a modern day detective series with great personable characters. Very easy to listen to. Despite her crappy views, Rowling’s way of writing is very clean and simple so might fit your brief.

I always recommend Diskworld

Please... for all that is good... listen to world war z, and the dark tower series.

I don't know if this is suitable for your needs, but I really enjoyed this reading of the deathworlders:

I’ve been really enjoying re-reading The Hunger Games series, and the Uglies series by Scott Westerfeld
