Lucy gets everything put away and sits down and surveys her half of the room. 

She brought a lot of books with her. Nothing that she only had one copy of; or rather, if she wanted to bring a book with her, she made sure to have it copied before she came. She's aware that this place is dangerous. 

(Other things besides her books and the clothes that went in her great wooden wardrobe have been hidden in various places less obvious than under the bed.)
