When Cammie thought she'd finally gotten a handle on the dangers lurking around Gallagher Academy, the stakes get impossibly higher—a shocking betrayal in London shatters her ability to trust anyone, even those closest to her. With a rogue double-agent hiding in plain sight and an ancient terrorist organization still circling, Cammie realizes that her greatest weapon, invisibility, is suddenly useless when the real threat comes from within. As she and her friends dig into dangerous secrets and uncover troubling truths about the past, Cammie must figure out who she can truly rely on before it's too late. This pulse-pounding installment takes everything you love about the Gallagher Girls and cranks up the tension, proving that sometimes the most dangerous spy game of all is the one played by people you love.
