I think my main problem with this book was that I loved the first book so much, that I wanted it to meet and exceed how much I enjoyed it. But it couldn't. I already knew a bit about the puzzles and clues and behind the scenes magic from the first book so I didn't have that same thrill. This was certainly a fun and quick read and still contains my favorite things (puzzles, games, libraries, and book facts). But I thought the story was a little "meh" at points and that sometimes problems wrapped themselves up just a little too neatly. Don't get me wrong, I did enjoy this book and will likely read any more books that come from this series, I just wanted more (greedy me).
