I'm not sure I'm rational about audio books, people, at least not yet. I'm still not very used to them.
The first audio book I'm listening to through my tablet is H. Rider Haggard's Eric Brighteyes, borrowed from my library (also available via Project Gutenberg. I've meant for years to read this, a homage to Old English and Icelandic sagas, and my county library has the book only in this format. Narrated, it's 10-and-three-quarters hours. I've listened to it at 1.25x speed, and reached the six-and-a-half-hour mark (just past the 8-hour mark as of Monday night). I'm thinking of re-listening once I'm done, maybe multiple shorter excerpts at a time. I'd have time; like other library items, I can borrow it for three weeks. (Digital material like this and ebooks can't be renewed.)
I still hope to see how well I retain a novel told to me, as opposed to one I've read. Some people don't retain stories well that way. I'm thinking of my Grandma Jean, my dad's mom, after she'd had a stroke; it was more annoying for her to hold a book, so I suggested to her that she get audio books. She turned that down, saying she wouldn't remember what she'd heard. Will I be like her that way? Let's see!
