If You Knew Jack

Sequel to You Don't Know Jack

Jack Carlisle has returned to the Center after an assignment designed to push him to the edge of his limits—and beyond. He is given just a few short days to get used to a new identity and a new team. He's been trained to assume a new identity, but working with a new team is more difficult, especially since it throws him back in the path of Leo McCormack, the boy who stole Jack's heart and handed it back broken into tiny pieces.

With "Jack Carlisle" dead and "Jack Cross" reborn comes a new mission. Jack Cross and his team are sent undercover to Forbes Academy, an elite boys' school in rural Connecticut. Here they must protect Adam and Sam North, whose lives are threatened by an unknown source.

Jack's training never prepared him to deal with the animosity he still feels toward Leo, but he knows the only way to figure out the cause of the danger in time to save Adam and Sam is to work together.
