From earliest memory they've been taught to hide, to hunt, to survive. Jack and Jill, feuding twins who can never stop running. Clare, mentor more than mother, steeped them in the art of espionage, honed their skills in weaponry, surveillance, and sabotage. But as they grew older they came to question her motives, her methods--and her sanity . . .

Now twenty-six, the twins are trying to lead normal lives. But when Clare goes missing, they realize her paranoid delusions are real. A twisted trail from the CIA to the KGB will lead them to an underground network of global assassins where hunters become the hunted.

Where everyone wants them dead . . .
