Robbed on the train platform as soon as he arrives in the city, eleven-year-old Oscar Starling soon finds himself in the middle of the Great Chicago Fire when he chases after his thief, who is herself in need of rescue.

A twelve-year-old street urchin and the son of Chicago's most important jeweler strike up an unlikely friendship in the days before the Great Chicago Fire of 1871, and both are nearly trapped when the city goes up in flames.

"Emmi, a German immigrant, is living in Chicago when the Great Fire breaks out on October 8, 1871, and, separated from her father, she finds herself with her neighbors, Cara and Seamus, braving the smoke and flames trying to escape the danger of the burning city, and searching for all their parents." --
