The last thing FBI agent Will Brody remembers is the explosion. He wakes without a scratch. The building is in ruins. His team is gone. Outside, Chicago is dark. Cars lie abandoned. No planes cross the sky. He’s relieved to spot other people --- until he sees they’re carrying machetes. Claire McCoy, the head of an FBI task force, stands over the body of Will Brody. A terrorist has claimed 18 lives and thrown the nation into panic. Against this horror, something reckless and beautiful happened. She fell in love…with Will Brody. But the line between life and death is narrower than any of us suspect --- and all that matters to Will and Claire is getting back to each other.
