Book excerpt: "After coordinated terror attacks take place at dozens of locations around the United States, including Grace Hardwick's university, she knows that there was a reason her father gave her a key that she constantly wears around her neck. Her dad is a science fiction writer and she knows that he would not let her go hundreds of miles from home with no backup plan. With her roommate in tow, they embark on a treacherous journey, not sure where they'll end up."--Publisher description.
