Wow. That is... a lot of books.
A small rowhouse - unit 121 on Gravel street. Typical of certain neighborhoods it's rather long and very narrow, with the house proper stacked on top of a garage and storage area. It has a modest backyard (though most of it is actually to one side of the home).
Each of the girls have their own room, but the caveat is there is a single bathroom shared across the whole house. This can cause some angry banging on the door. The home is also approximately 1/3 bookshelves. There's barely any kind of organizing to them (they're taken in and put back too often to warrant it), and have a whole host of things from research books, fiction, biographies, textbooks, and all things in between.
