I looked into her eyes, and saw my own staring back, the same peculiar shade, pale grey, flecked with yellow, rimmed with black. Now I knew the nature of her debt. It had weighed on her conscience for fourteen years. I was looking into the eyes of mother and I knew that I would never see her again.

There are patterns in everything, in the whole of Nature, from the way the stars turn in the heavens to the whorl of a shell or the petals of a flower and the way leaves arrange themselves about a twig. There are forces, hidden forces. If I can discover what they are, how they operate, I will have my hands upon the levers of creation and can work them myself.
