I'm a HUGE fan of audiobooks these days. One of the side effects of chemo some 15 years ago was a rewiring of my brain, such that I no longer have the attention span to read the written word as I used to. I've gone from reading some 50 odd books a year to one or two. I can, however, stay focused on audiobooks and audiodramas, and I literally jump on the Black Library audio bundles on Humble Bundle when they drop. I'm a huge fan of the Warhammer and Warhammer 40k universes, and getting the fiction in an audio format at a buck a book is a win-win for me :)
You can snag the Voices of Warhammer 2021 Bundle for as little as a buck for 5 books, but since you can sample them all, I advise you listen to a sample or three for free and see if the format works for you. If it does, 18 bucks get you all 19 books (although admittedly, one is a sampler). At a buck an audiobook, if you enjoy the format you simply can't go wrong.
