The Brother's Story by Katherine Sturtevant

  Another good example of why I really like reading historical fiction is this book.  This story takes place in what is still believed the coldest winter in England's history - 1683-84.  The main character, 15-year-old Kit, leaves his dreadful life in a small village in Essex, to better himself in London.  He leaves behind his mother and twin brother, Christy, who is "simple."
  The enormous struggle of the poor and the wretched treatment they received, is powerfully presented, and again, the reason I love historical fiction so much.  Only the hardest heart out there is not going to empathize deeply with Kit and the situation he finds himself in and want to help somehow. Kit also has internal struggles on many levels  He is passing through adolescence; trying to control his feelings and passions while remaining an honest and virtuous person.
  A very well told story, and I am SO glad I live when I do!
