The Invisible Spy By Lisa McMann

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?
