3rd World Products, Book 15

Aria Wilson is an eight-year-old eleventh-grader at the Amaran asteroid factory station. As if her exceptional intelligence wasn't unusual enough, she exposes herself as a natural field user when she saves another kid's life at a birthday party. Shocked and alarmed school and station officials immediately ship her to Earth, where Lori and Ed have to foil the federal government's attempt to take seize possession of Aria with a phony Child Services warrant. Ed, Lori, Aria, and her mother manage to escape government custody and end up on the run as they put together a plan to keep Aria from becoming a human lab rat.
