A man Called Box

Sam thought the worst part of living alone was the loneliness. She was wrong.

A decision based on compassion, which will soon change her life, force her to abandon everything and flee to avoid being killed.
But hiding and leading a lonely, anonymous life locks Sam into a situation she cannot resolve. 
Thomas, searching for his long lost sister, finds a fugitive living alone in the mountains. Two stubborn people surrounded by danger and distrust, in a situation where one misstep will get them killed.
Who can you turn to if even police can't be trusted? And who is the man called Box?
