The Mayhem Dividend — Scott Johnson

Tim Ellingwood has a penthouse apartment, an overpaid job, and a knock-out girlfriend. It's just enough to keep him happy, so long as he can soak the haunting memories of his time overseas in enough booze and sex to keep the voice in his head quiet - without drowning his own soul first. Then he meets Will Flint, a mysterious neighbor who convinces him to try for more, but it will cost him. They risk everything and set out on an epic adventure that takes them from high in the thunderous Rocky Mountains to the blood-soaked streets of Kyiv as the two confront a violent and deepening conspiracy that entwines both their past lives. Can Tim and Will run the gauntlet and come out alive?
