Amy Foster, now known as Natalie Freeman, is Sophie Foster's human sister and makes appearances in Book 1 and Book 5.
She is given the name Natalie Freeman after the washers erased her memories. Sophie frequently checks on them with a 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 Natalie (Amy). 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 make her mind silent.
