This ended up being a solid 3 for me as it dragged so much but i was intrigued to find out what the mysterious ink was and how the librarian and the no longer librarian where going to make things work. Then we got to visit new part of the realm like the forgotten wing where books that have been forgotten due to being the last copy, no longer published or the author has died. Then you have Hero trying to figure out what he is without his book and the mystery inks seeps into Claire arm. So there was a lot to suck me in but just seems like it was mixed into a confuluated narrative but the ending got me enough that I want to know how it all ends. Not as solid or as enjoyable as the first book.
