Amy Rose Foster, now known as Natalie Freeman in the human world but allows Sophie to call her Amy, is Sophie Foster's human sister and makes appearances in Book 1, Book 5 and Book 6
She is given the name Natalie Freeman after elvin Washers erased her memories. Sophie frequently checks on her, as well as the rest of her family, with an illegal Spyball in the first book. At the end of Lodestar we find out that the Neverseen attacked and kidnapped Sophie's human family; Sophie and Fitz searched the house and found a terrified Natalie (Amy) hiding. Amy somehow still remembers her and calls out "Sophie?" It is shown that Amy knows how to make her mind silent because she overhears the Neverseen talk about listening for thoughts and is able to stay undetected. Many fans believed that this was proof that she was an elf, and several guessed that she might be Lodestar Initiative. In Nightfall, however, Amy gets her memories of Sophie back and is revealed to be only human, but is very helpful even when told to stay out of the whole Sophie's-human-parents-are-kidnapped-and-being-held-at-Nightfall business.
