What are the unseen forces that make a survivor of one man among many?

It had been one of the worst crashes in airline history, killing more than 300 people and leaving only one survivor. Now the dead were buried and the town of Eton tried to forget, but one man could not rest. Keller had walked from the flames of the wreck, driven on by unseen forces, seeking the answer to his own survival. The town was soon forced to face the shocking, dreadful truth about what was buried in the old graveyard--a truth Keller did not want to believe.
