Puppet Master by Dale Brown, Jim DeFelice

New York Times–Bestselling Authors: A roboticist aids the FBI in fighting Eastern European criminals using AI—until things go very wrong . . .
Louis Massina is revolutionizing the field of robotics. His technological wonders are capable of locating disaster survivors, preventing nuclear meltdowns, and replacing missing limbs. After one of Massina's creations makes a miraculous rescue, an FBI agent recruits him to pursue Russian mobsters running a massive financial scam—and not coincidentally, suspected of killing the agent's brother.
Massina agrees to deploy a surveillance bot that uses artificial intelligence to follow its target. But when he's thrust into a dangerous conspiracy, the billionaire inventor decides to take matters into his own hands—unleashing the greatest cyberweapons in the world and becoming the Puppet Master . . . .
