What would you risk to save a life? Jim's fall break is supposed to be relaxing, not take him time-traveling again. And then he discovers something awful that will change his friend Hannah's life back in 1838. Hannah Cooper has more than enough trouble. It's bad enough that she has to do the heavy farm chores while her father is helping build a canal. It's worse that she's hiding a secret friendship with a poor Irish girl. When Jim shows up, he can't tell her the truth: that Hannah's father - an ancestor of his - is about to die in a fire. What can he do but stay close to Mr. Cooper and try to prevent the fire? Jim braves bone-chilling cold, giant draft horses, and rising tension between townsfolk and Irish immigrants. But all his efforts might be for nothing when someone else goes missing. What's more important: the past or the future?
