" Stamp, your name is to be Laura. I'm sharing my name with you. I'm putting my power into you and you must do my work. Don't listen to anyone but me. You are to be my command laid on my enemy. you'll make a hole in him through which he'll drip away until he runs dry. As he drips out darkness, we'll smile together, me inside, you outside. We'll crush him between our smiles. "

― Margaret Mahy , The Changeover
