Nothing wrong with audiobooks! It’s my preferred way to consume my books. Also if I didn’t listen to audiobooks, then I would never have experienced TGR’s glorious performance in the Red Rising series. I don’t think audiobooks are better for every book, but in the case of Red Rising, I would argue it’s mandatory.
I just finished Lightbringer myself and I absolutely loved it. I’m equally devastated knowing how long it’ll be before we get the next one!
