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

Only weeks remain before the election that will decide the fate of supernaturals in Estero, with presidential challenger Magdalia Palacio in the lead. Desperate to maintain his grip on power, corrupt President Fuerte has leaked photos of the forgotten five to the press, making the kids public enemy number one. And now the location of their safe house has been discovered, and the five and their friends are on the run.

With their identities revealed to the world, the kids must master the art of disguise to move freely about Estero, including infiltrating an upcoming Fuerte campaign event at the Estero City Zoo. But the other side is willing to play dirty, so the five will have to be ready for anything.

Meanwhile, Cabot's parents, who have been acting as double agents for years, dare to cross the president and are arrested, leaving them unable to share critical information: Fuerte has a new super on his team with the power to change the course of the election--and no one will see it coming until it is too late.
