An icy, dark night.
Danger on the mountain.
A speeding train headed for destruction.
 
It's just after 4:00 A.M., April 29, 1903, in the coal mining town of Frank.  Nathalie Vaughan lies awake - listening for the train whistle.
Her cousin Helena will be on that train.
Moments later, disaster strikes, bringing terror beyond anything Nattie or her neighbours ever imagined.  No one is prepared.  Everyone must lend a hand.
Thirteen-year-old Nattie has to find the strength and courage to help save her friends' lives.  Then she remembers Helena and all the people on the train.
Who will save the train?
