In the series
During Death Masks, Amanda is five and a half years old. She has tow-colored hair. When Dresen visits the Carpenter home and introduced himself to her, she names him "Bill" as they already had one Harry.
She has grown to a high-school age young woman, about as tall and attractive as her older sister Molly, causing Harry Dresden to imagine she might cause neck injuries to boys turning their heads to watch her. Much to her sister's dismay, she wears school uniforms also at home.
