Once there was a girl named Marsha Stitt. One day she would become Marsha La Vine, but that was a long way off. This happened years before all that, back when Marsha was a small girl living in the country.
Little Marsha loved three things. She loved cookies; she loved books; and she loved staying up late. Her favorite activity combined all three. When her parents went to bed she would stay up late and read under the covers. She was afraid the lights would wake them up (they didn't approve of her late night book-worming).
As she read stories of horses and orphans she would think to herself, "This book is nice, and it sure is pleasant staying up late to read it, but you know what would make this even better? Three cookies."
So she would sneak out to her mother's big fridge (the one that held the dozens upon dozens of pre-made-then-frozen cookies), undo the elaborate and supposedly kid-proof rubber band seal on the plastic bags of cookies, and take exactly three.
Back in her room she would place the cookies one at a time on the opening on top of her bedside lampshade. Within minutes the lightbulb's heat would bake the cookie to near perfection. Then, with cookie in hand (and mouth) she read all through the night. Fueled by delicious homemade cookies, she read the stories that fueled her imagination, until it became too late even for her. Her little eyelids fluttered, and she fell asleep, dreaming of all the wonderful things she would do.
