For many years it's been ebook mainly because of limited space and aging eyes.
But strangely I just picked up a trade paperback at Barnes & Noble that I'm liking reading very much, not just for the story but for the tactile nature of it. I've read my whole life and never thought I'd ever trim my library. But having kids and getting older abused me of that notion. ๐
I'm still going to use my Kindle for most books, but it's been nice to have a physical book again.
Kobna Holbrook-Smith was the narrator that taught me an audio book performance can truly enhance the books. Even though I still buy the ebooks of Ben Aaronovich's Rivers of London books, I listen to the audio books first.
