Fictional dictionaries on Kindle finally helped me get through Tolkien

Growing up, my dad and I bonded over sprawling fictional universes (in case anyone wondered how nerds are created). He got me to slog through the entire Dune saga, his personal favorite, which I enjoyed but also consider a heroic act of filial love. Every time he brings up Tolkien, though, I stall out. And then a colleague told me about fictional dictionaries, or “Fictionaries,” on Kindle.
