Practicality, and Potter

Here's the thing: I'd read all the Harry Potter books. I'd watched all the movies, and devoured them at the time. But I'd left them behind at age twelve, preferring physics over Pottermore and dreams of Cambridge over those of Hogwarts. Then again, here I was: Sophie Roper, a plain Gryffindor in Hermione Granger's dormitory with absolutely no idea of how I got here. (SI, kind of.)
