Threat Warning (A Jonathan Grave Thriller, 3)

The first victims are random. Ordinary citizens, fired upon at rush hour by unseen assassins. Caught in the crossfire of one of the attacks, rescue specialist Jonathan Grave spies a gunman getting away—with a mother and her young son as hostages. To free them, Grave and his team must enter the dark heart of a nationwide conspiracy. But their search goes beyond the frenzied schemes of a madman's deadly ambitions. This time, it reaches all the way to the highest levels of power.
