Aurora Moon is Hawkins High’s golden girl — beautiful, brilliant, chaotic, and impossible to ignore. Between running the student council in perfect heels and owning the trendy science-food shop Moon Bites, nobody suspects that the dreamy Brazilian teen is secretly a scientific prodigy connected to a hidden organization. Armed with her pink holographic A.D.I.S.O.N. tablet and a mind full of bizarre inventions, Aurora is used to balancing popularity with genius. But when dangerous experimental technology begins appearing around Hawkins, she’s pulled into a mystery involving secret agencies, supernatural events, and inventions powerful enough to destroy the town. Now, with Dustin obsessed with her gadgets, Robin constantly teasing her, and Steve Harrington somehow ending up in the middle of every mission, Aurora’s carefully balanced double life starts falling apart. Especially when feelings become harder to hide than the secrets on her tablet.
