War Machine — Jeffrey Wilson; Brian Andrews

In Sons of Valor III: War Machine, Chunk and Whitney are forced into a deadly match of wits with a terrorist mastermind and a terrifying weapon unlike anything they've ever encountered.

After a shootout in Dubai left Hamza al Saud dead and elevated brilliant aeronautical engineer Qasim Nadar to hero status in England, everyone assumes the terrorist threat from al Qadar has been eliminated. Everyone except JSOC counter-terrorism analyst Whitney Watts. But when she decides to help MI6 penetrate Nadar's secret network, Watts she gets a little too close to the truth and finds herself in a deadly situation not even her teammates from Tier One can save her from.

As Lieutenant Commander Keith “Chunk” Redman and the rest of Tier One fan out across London in search of Watts, Nadar prepares to unleash his most dangerous weapon yet -- an advanced drone with artificial intelligence and stealth technology. To stop a horrifying attack on London, Chunk and his Navy SEAL brethren must seek help from an unexpected ally and find a way to stop a war machine that was designed to be unstoppable.
