X-Men meets Spy Kids in the third installment of The Forgotten Five middle-grade fantasy/adventure series by the New York Times bestselling author of The Unwanteds. Now in paperback!

Estero City is in an uproar following the exposure of President Fuerte as a supernatural, as well as the surprise announcement by Magdalia Palacio—Seven’s mother—that she will oppose Fuerte in the upcoming election. The forgotten five and their allies know the president is corrupt to the core. But no one knows if Magdalia can be trusted.

Meanwhile, Birdie, Seven, Tenner, and Brix are reeling from Cabot’s decision to leave the group and join her parents, who are collaborating with Fuerte and his gang of supernatural criminals. Does that make Cabot their enemy, too?

Still, there’s work to be done. The Librarian, the five’s trusted confidante, has a daring new plan: Lada will go undercover and pretend to work for the president while gathering intelligence for the supernatural resistance. It’s a dangerous assignment, setting the group up for a showdown with their most powerful enemy yet—their own criminal parents.
