I recently finished up Tomorrow, and Tomorrow, and Tomorrow and was surprised by how much I enjoyed it! I got the impression, for whatever reason, that it was overhyped. But I enjoyed seeing how the characters developed and seeing the ebbs and flows of their relationships, which I thought was well done and believable. There was a lot more depth there than I was expecting. I also thought it was going to be more of a traditional love story and was (pleasantly) surprised that it wasn’t!
Another surprise for me was The Silmarillion. I’m a fan of LotR, but I still expected it to be a bit of a slog. But, wow, I tore through that book so quickly! Loved the stories and lore and mythology and everything, incredible!
