Spoiler warning!
This article contains plot details from the latest book.

The Foster family is the human family that raised and took care of Sophie when the Black Swan left her with humans. They believed Sophie was their biological daughter and did not know that she was an elf or a Telepath. The Elves had planned on faking Sophie's death so that she could come to live with them secretly, but Sophie requested to Alden that they wipe their memories instead because she didn't want them to live with the pain of thinking their daughter was dead. After that, Sophie watches her family (with new names) with her illegal Spyball, given to her by the Black Swan.

At the end of Lodestar, Sophie checks on her family because she believes the Neverseen have done something to them and finds her sister hiding. At the beginning of Nightfall, her sister learns all about elves and about Sophie's world.
