I loved this one. It's admittedly a bit derivative of other great books - the opening chapters must have been inspired by the opening of his dark materials (before she leaves with Mrs. Coulter). But mostly the book has major Howl's Moving Castle vibes. There's Elisabeth, a girl raised in a magic library, who has to rely on Nathaniel Thorn, a sorcerer with some some dark backstory, and his demon servant/sidekick Silas. It's a fun world full of sorcery, demons, and magic sentient books (that can turn into monsters)! The romance didn't overpower the book, but was still very much present and well-done. A lot of the time, you could tell exactly where the story was going and you were just waiting for one of the characters to catch up, but it was still a lot of fun. Also love the casual queerness.
