The guardians, the shadowy heroes of the top-secret
program designed to protect members of the most
elite government organizations, are being hunted
down one by one. There is a single explanation: a
traitor must be embedded somewhere in their midst.
But if they themselves are the target, who will
protect them?
CIA operative Renee Niezen has heard tales of the
guardians, though she's never really believed in their
existence—until she is approached by Charlotte, an
old friend who desperately needs her help to stop the
systematic destruction of the guardian program.
Renee accepts the plea for assistance, but not
everyone is thrilled to have her on the team. Kade—one of the last guardians standing—is unimpressed
with Renee's qualifications and turns instead to the
legendary Saint Squad for help. But when Renee is
caught in the crosshairs, Kade must set aside his
antagonism for the woman in order to protect her.
Their grudging alliance soon develops into much
more—but before the pair can examine their
feelings, their investigation takes a dramatic twist.
With lives on the line, Renee and Kade must use
their spy training at every turn as they draw
dangerously close to the shocking truth.
