Tom and Megan Stark always thought there would be time—time to have children, time to take that trip to San Francisco, time to fix the problems in their marriage. But Megan's illness and Tom's inability to face the possibility of losing her are stealing all the time they have left. All Tom can do is bury himself in his job as a train conductor, where at least he feels in control and everything runs on a predetermined track. Until now. Tom's train has hit a car on the tracks in a tragic turn of events that, while not his fault, may still cost him his job. Worse, a young woman is dead and her son, Davey, has been left to cope with the loss of his mother, the guilt that he could not save her not only from the train but from herself…and the anger at the man he holds responsible: Tom Stark. The accident puts the Starks and Davey on their own collision course. But instead of leading to tragedy, this crossing could mean new hope for a woman who has only one chance left to fulfill her dreams, for a man who must learn to open his heart before it's too late, and for a young boy who has never known the true meaning of family.
