X-Men meets Spy Kids in the fifth 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 are reeling in the aftermath of the raid on Magdalia Palacio´s campaign rally-an attack masterminded by her corrupt opponent President Fuerte and his henchmen. Birdie is in the hospital with a head injury, and under arrest for stealing a police horse in her attempt to evade capture. Separated from her friends-and not even allowed to see her mother-how can Birdie escape when she is utterly alone? Then the Librarian is taken captive in the heavily guarded palace dungeon after Fuerte discovers she´s been acting as a double agent. What will they do without their trusted mentor? Luckily, the five have been honing their supernatural abilities, and it´s Brix who takes the lead, forging an unlikely alliance and putting together a plan. Does the group have what it takes to rescue their friends and even the odds in the president´s all-out war against Estero´s supernaturals?
