Getting home has never been so treacherous

When an EMP takes down the power grid and everything that runs on a computer chip, Melissa has no choice but to walk from her office in downtown Salt Lake City to her home in a suburb twenty miles south. With a few co-workers to keep her company, she isn't too worried—until they begin their journey and discover how quickly society can fall apart.

Alex, Melissa's husband, works thirty blocks south of Melissa's office. When everything stops working he has to decide whether to head north and find Melissa or go in the opposite direction to see if their teenaged children made it home. Only trouble is, he's by himself and danger is everywhere.
