I bet you were hoping for something more profound, hmm?
Truth is, my lived experience is not all that profound. Books were sanctuary for me when I was growing up. I spent a lot of time in the public library, and then I went home and read some more. Books were instructional and safe and dependable. I guess you could say books raised me, so I think of them as a beloved granny maybe, not a magical portal or secret religion. Or, as Oprah Winfrey put it, "Books were my pass to personal freedom."
So in a sense, the truest truth would be to say that books are practical magic.
