Left behind alone on the island are their children: There's Birdie, who can communicate with animals. Brix has athletic and healing abilities. Cabot is super-smart, but there's no sign yet of her special ability. Seven's skin camouflages to match whatever is around him. Tenner can swim like a fish and has heightened senses, including the ability to see in the dark. When Birdie finds a map with a set of instructions directing her to a stash of treasure that's secret from everyone—including their missing parents—she knows it holds the power to change everything, for better or worse.

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?
