Power Play — Joseph Finder

It was the perfect retreat for a troubled company. No cell phones. No BlackBerrys. No cars. Just a luxurious, remote lodge surrounded by thousands of miles of wilderness.
All the top officers of the Hammond Aerospace Corporation are there. And one last-minute substitute -- a junior executive named Jake Landry. He's a steady, modest, and taciturn guy with a gift for keeping his head down and a turbulent past he's trying to put behind him.
Jake's uncomfortable with all the power players he's been thrown in with, with all the swaggering and the posturing. The only person there he knows is the female CEO's assistant--his ex-girlfriend, Ali.
When a band of backwoods hunters crash the opening-night dinner, the executives suddenly find themselves held hostage by armed men who will do anything, to anyone, to get their hands on the largest ransom in history. Now, terrified and desperate and cut off from the rest of the world, the captives are at the mercy of hard men with guns who may not be what they seem.
The corporate big shots hadn't wanted Jake there. But now he's the only one who can save them.
