In the dead of night, there's a knock on the door at Haven, an inner-city youth center in St. Louis. A refugee family—scared, tired and hungry—seeks shelter. Fresh back from Afghanistan, former marine sergeant Joshua Duff takes on the mission. He recruits aid worker Liz Wallace, but she has questions for Joshua. Such as why a Texan with an oil magnate for a father is working at Haven. Or why a man who fears nothing—including the gang violence threatening the center—seems scared of opening his heart to her.
Joshua will call upon his training and his faith to protect Liz and Haven. Yet the most dangerous threat lurks closer than they realize.
