Sophie slung her schoolbag on the floor and put a bowl of cat food out for Sherekan. Then she sat down on a kitchen stool with the mysterious letter in her hand. 

Who are you? 

She had no idea. She was Sophie Amundsen, of course, but who was that? She had not really 
figured that out—yet. 

What if she had been given a different name? Anne Knutsen, for instance. Would she then have been someone else? 

She suddenly remembered that Dad had originally wanted her to be called Lillemor. Sophie tried to imagine herself shaking hands and introducing herself as Lillemor Amundsen, but it seemed all wrong. It was someone else who kept introducing herself. 

She jumped up and went into the bathroom with the strange letter in her hand. She stood in front of the mirror and stared into her own eyes. 

“I am Sophie Amundsen,” she said. 

The girl in the mirror did not react with as much as a twitch. Whatever Sophie did, she did exactly the same.
