The most pressing issue on Adam Hayes' mind is planning his son's upcoming fifth birthday party. After years of operating in the world's most dangerous spots for Treadstone, he's ready to call it quits, but the feeling isn't mutual. Levi Shaw, Treadstone₂s director, calls Hayes back for one more mission. It's a walk in the park. You don't even have to go in with the strike team. I just need you to set up the safe house. You₂ll be home in time to pick up the birthday cake.₄ But nothing is ever easy where Treadstone is concerned. When the mission is blown only Hayes is left alive, and everyone, it seems, is determined to correct that oversight.
