This was fine! I read it! I was an 80s teen/young adult and I used to live in London, so I enjoyed those parts of the scene. But this didn’t grab me and I’m not sure why. Too many characters? Not enough time with Merlin? And this is niche, but: the bookseller idea is fun—I’m all in favor of thinking about booksellers as long-living mystical families—but it wasn’t integrated into the story. They could have been clock repairers and that might have made more sense.
