Hit it the other day, in mid-October, kind of ironically, with The Things You Can See Only When You Slow Down by Haemin Sunim.
Truth be told, most of these books - maybe three quarters or more - were listened to.
I drive at least an hour each weekday, usually more. Listening to books at 2x speed, that's 10 hours, which is maybe a little more than an average book's length. (Given, Stephen King's latest monster, Sleeping Beauties, was 28 hours.)
Audible has a daily deal, always advertised in their banner, a full book, usually decent titles, usually $3.95 or less.
And I download a lot of audiobooks free from my library with the Overdrive app - I'm surprised how many people don't know you can do this. There are wait lists for a lot of the good ones, but it's worth it.
