1- So, The Invisible Library is about Irene, a spy for a very mysterious Library, and her quest to retrieve a dangerous book from an alternate London 
 2- It's a really good read-alike if you like the Eyre Affair...but instead of going into books, you're going into parallel dimensions and alternate worlds to take their books for the sake of preservation and research 
 3- The library has a life of its own, and the librarians seem like an interesting bunch 
 4- I really want to know more about the librarians. We get a little bit of the hierarchy and structure of the library, but not a lot, and I'm hoping we get more 
 5- The way I feel about the librarians is the same way I feel about the Library. We get a general idea of the library and how it works but I want more 
 6- It is the first book in a series, so it is setting up for future books. Hopefully we'll see more of the library 
 7- There are a lot of possibilities, though. I mean, they go into parallel dimensions to retrieve books, and there are a lot of possibilities for future books. It would be interesting to see how things could possibly spiral out 
 8- My Rating: 3 stars. It's a fun book to read, and great if you like books about books and libraries, but I wanted more about the Library and the librarians who work there.
