The whole truth / David Baldacci.

Enhanced descriptions from Syndetics:

Dick, I need a war, Nicolas Creel is a man on a mission. He heads up the world's largest defense contractor, The Ares Corporation. He's retained Dick Pender to perception manage his company to even more riches by manipulating world conflicts. Shaw (no first name), a man with a truly unique past, travels the world reluctantly doing the bidding of a secret multi-national intelligence agency in order to keep the world at peace - and safe. Katie James, a journalist who will do anything to get back to the top of her profession, has just gotten the break of a lifetime, the chance to interview the sole survivor of a massacre that has stunned the world. In this terrifying thriller with a global backdrop, these characters' lives will collide head-on as a series of events is set in motion that could change the world as we know it. An utterly spellbinding story that feels all-too-real, THE WHOLE TRUTH delivers all the twists and turns, emotional drama, unforgettable characters, and can't-put-it-down pacing that Baldacci fans expect-and still goes beyond anything he's written before.
