On the heels of her soaring bestseller Flight, Edgar Award-winning author Jan Burke reaches new heights of suspense in this ingenious novel of hard-hitting justice and cold-blooded murder. Los Angeles County Homicide Detective Alex Brandon lives to bring killers to justice—but when unknown assailants begin systematically killing off the FBI's Most Wanted suspects, Alex sees no cause for celebration. The vigilante slayings eerily echo the work of a serial killer from a decade ago, and convince Alex that "the Exterminators," as a grateful public has dubbed them, are more ruthless and sadistic than their victims. As the attacks mount, it is the ninth target that pulls Alex into a case that is quickly spiraling into deadly territory—where justice is no longer enough.
