Very cool premise about books containing magic! And the characters were delightful. I loved the mirror magic conceit too. I would likely be interested to read more in the world if there’s a sequel, but I do have some major hang ups around blood that made the reading experience challenging at times. Honestly I can’t write more about it because it makes me feel sick, but I’m a baby about this. If you don’t feel squeamish and you like magic/fantasy/books about books, you’ll love this!
