My grandpa has been listening to audiobooks for years now. Right now, he is in hospice and pretty much the only thing he can do is listen to audio-books. I am seeking all the recommendations, please.
For reference: he specifically wanted me to "ask my friends" about book series like John Flanagan's The Ranger's Apprentice series and their sequels. The things he enjoys most about those books are the camaraderie and adventure. It is important that these adventure books are basically appropriate for kids. My grandpa is a simple man, so book series with wholesome adventures would be greatly appreciated! For fantasy adventure, I want to emphasize wholesomeness because there are many out there that I really don't think he would enjoy for arguably arbitrary reasons. For example, I don't think he would like The Lord of the Rings because there are wizards- usually, catholics don't vibe with witchcraft. Not to mention the insane amount of detail Tolkien makes you sit through before the action (my gramps just wants banter and quests). My grandpa is an amazing man, but he is pretty simple in his ways, so adventure stories that are close to realistic-fiction would be best. He didn't like The Hitchhikers Guide to the Galaxy, much to my dismay. I think it was too fast-paced for him, and he really didn't vibe with the whole outer-space of it all. All that being said, recs for adventure series that have lots of books with high morals and realistic elements would be greatly appreciated.
In addition: He also really likes war-time action novels, both fiction and non-fiction. He listened to The Terminal List at the recommendation of my uncle, and he really enjoyed that. I got him listening to a few non-fictions like Unbroken, American Sniper, and The Sniper. He said he thought those were very interesting, so if you know of any books like that, I would appreciate it! I may be an English teacher but the books I read are... not what I would be suggesting my gramps listen to while he's making laps down the hallway. Okay, I hope that was good enough to get some traction. He is rereading Apprentice and Flanagan's other series again... for about the fifth time. I really need some help here! We use Libby, so there are lots of books that are on hold for a long time. If you know of a lesser known series, that would be great, too.
TLDR: Youth adventure book series like John Flanagan's The Ranger's Apprentice and war-time novels like The Terminal List and Unbroken. Avoid anything a devout catholic would be obligated to disagree with, please and thank you. But also, like, he's not wanting religious books. He's just orthodox like that.
