Hidden Among Us

Fifteen-year-old Selene Calloway thought her world was high school in West Los Angeles, a backyard telescope, and dreams of studying the stars. But as Selene approaches her 16th birthday, she is drawn into a hidden universe of secret agencies, alien civilizations, and impossible machines built around stars themselves. Officer Kevin Brooks has seen one thing he cannot explain — and now Department 42 wants him for a job no one sane would accept. Aliens are real. The Aurelian Empire spans fifty two thousand light-years, commands city-sized warships and Earth-sized space stations, and harvests stars with an actual dyson sphere.  His assignment, to babysit Selene as she navigates her path to an interstellar civilization of impossible size and technology.
