X-Men meets Spy Kids in the thrilling second installment in The Forgotten Five fantasy/adventure series that began with the instant New York Times bestseller Map of Flames . The forgotten five have made it to Estero to search for their missing supernatural criminal parents. With the help of their new allies, Lada and The Librarian, they’ve managed to find Birdie and Brix’s mother, Elena, and free her from captivity in the presidential palace. Now the president’s henchmen are searching everywhere for the children who broke out Elena, driving the group into hiding in the ancient underground tunnels beneath the city. Meanwhile, President Fuerte is making headlines for his nighttime flights to other countries accompanied by an invisible man. But why would the president who outlawed supernaturals be working with the people he supposedly hates? And could it be that some of the five’s own parents are helping him? The fantasy adventure that began with the New York Times and Indie bestseller Map of Flames continues as the five join the fight against the oppression of supernaturals in Estero, face off against an unexpected enemy, and undertake a new mission that will put all of their abilities—and their loyalties—to the test.
