This is not normally a story I would like; it goes nowhere ultimately, it's slow, it's plodding, it should be a 'meh' at best. The funny thing is that i really enjoyed it. I liked the premise, I liked that the library was as much of a character as the humans, but that the auther never went out of the way to make it so (nor even ever really explained it as far as I could tell), and I liked the premise of it all.
I can certainly think of worse places to live than in a magical library, although I don't know that I could grow up having never actually set foot outside, but as long as the library kept giving me new books, I suppose I could manage.
Next time I go to the library I shall have to feed it a cookie, and see if it will give me anything in return.
