Narnia was only the first adventure that Polly Plumber would have in her very rich life. She never again left the world she had been born in (at least not until that final train crash) but she found adventures: in college research labs, in trips halfway across the world, in hospitals during wartime, in museums and libraries and roller-rinks and orphanages and meeting rooms. Because something had awoken inside Polly Plumber while she was flying over a newborn country on horseback and there was never any going back.
