I’ve basically given up ‘paper’ books for them, I love them, re-read (listened) loads of stuff I already owned & thoroughly enjoyed them again from a different perspective. I’ve listened to more books over the last year or so, than I probably read in 5-10 years (& I read a quite reasonable amount).
I’m more likely to finish listening to a book I’m not really enjoying, than I would if I was reading it, so I’ve used this to expand my normal reading content (eg: older pre 20th century authors). I find you can do stuff like house work/cooking/gardening and driving whilst listening to them, so there loads more convenient.
As for recommendations, what do you normally read? I love my Sci-fi, so all my recommendation would be along those lines… so basically anything I’d normally read
