Amherst, 1857. The Dickinson family braves one of the worst winters in New England's history. Trains are snowbound and boats are frozen in the harbor. Emily Dickinson and her maid, Willa Noble, have never witnessed anything like it. As Amherst families attempt to keep their homes warm, fears of fire abound.

These worries prove not to be unfounded as a blaze breaks out just down the street from the Dickinson in Kelley Square, the Irish community in Amherst, and a young couple is killed, leaving behind their young child. Their deaths appear to be a tragic accident, but Emily finds herself harboring suspicions there may be more to the fire than meets the eye. Emily and Willa must withstand the frigid temperatures and discover a killer lurking among the deadly frost.
