i understand how she feels

I just finished "The Girls," by Lori Lansens, a novel about a set of conjoined twins. It was good, but not necessarily anything to write home about. I did like one thing that one of the sisters said, though, talking about her favorite books:
"I feel, holding the books, accomodating their weight and breathing their dust, an abiding love. I trust them, in a way that I can't trust my computer, though I couldn't do without it. Books are matter. My books matter. What would I have done through these years without the Leaford Library and all its lovely books?"
