The Mailman by Andrew Welsh-Huggins

Mercury Carter has a delivery to make to Rachel Stanfield. When Carter arrives at Rachel's house, he finds that Rachel and her husband Glenn are being held hostage by a guy named Finn and his henchmen. Carter just wants to make his delivery and leave, but Finn kidnaps Rachel and leaves with her before Carter can complete the task. Carter then finds himself, accompanied by Glenn, on Finn's trail trying to rescue Rachel because Finn is convinced that Rachel has information that he needs--and Finn is prepared to kill for it. The Mailman is the first book in a planned series and is perfect for fans of Thomas Perry, Lee Child, and Nick Petrie.
