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.

The Forgotten Five and their friends have been under increased scrutiny in Estero ever since Martim Palacio published his article revealing their identities and alleging they are armed and dangerous. Corrupt President Fuerte has been stoking anger against all supernaturals, in hopes of gaining public support for his reelection, and photos and videos have leaked of the kids from their most recent raid.

Things get even more complicated when the media discovers the Five's monastery hideout. Fearing their presence has begun to put the monks in danger, the group now must find a new home.

Then on the eve of the election, the Five get wind of a late-breaking campaign speech the President has planned at the Estero Zoo. Now that everyone knows what they look like, the kids must disguise themselves to infiltrate the zoo event and disrupt the proceedings. But it's rumored the President seeks to debut a secret threat at the rally: a super with the power to change the course of the election.
