Whatever happens, don't go Outside. Naya has been navigating the disappearing doors, shifting windows, and size-changing rooms of her indoor city her whole life. She will do anything to be accepted into the city's governing body and police force, the NSDE, and anything to make her mother, the General, proud. So when her mother asks her to take on a top-secret, dangerous assignment, to spy on the Spiravits, a dangerous enemy with powers no one understands, she accepts. Naya knew the risks in leaving the safety of her indoor home, but she never thought the Spiravits would be so human, especially as she starts getting closer to two siblings, Zayn and Anice. And that Outside would be quite so . . . wonderful. What if everything she thought she knew was wrong? How can she complete her mission when she can no longer tell truths from lies?
