In 1888, young Helen Keller traveled to Boston with her teacher, Annie Sullivan, where they met a man who would change her life: Boston Transcript columnist and editor Joseph Edgar Chamberlin. Throughout her childhood and young adult years, Keller spent weekends and holidays at Red Farm, the Chamberlins' home in Wrentham, Massachusetts, a bustling environment where avant-garde writers, intellectuals, and social reformers of the day congregated. Keller eventually called Red Farm home for a year when she was sixteen.

Informed by previously unpublished letters and extensive research, Letters from Red Farm explores for the first time Keller's deep and enduring friendship with the man who became her literary mentor and friend for over forty years. Written by Chamberlin's great-great granddaughter, this engaging story imparts new insights into Keller's life and personality, introduces the irresistible Chamberlin to a modern public, and follows Keller's burgeoning interest in social activism, as she took up the causes of disability rights, women's issues, and pacifism.
