This collection investigates the complex, often contradictory lives of the six Mitford sisters through their own extensive correspondence, revealing the internal dynamics of a prominent 20th-century British family. Editor Charlotte Mosley provides the necessary biographical context to navigate the sisters' divergent political paths and personal lives, using their letters as a primary source to document the shifting social landscape of their era. The work serves as an intimate record of how these women navigated the pressures of aristocracy, war, and ideological extremism.

The text offers a dense, meticulously curated look at the private lives of a family that occupied the center of British political and social discourse. The scope of the correspondence provides a valuable, unfiltered perspective on the personal consequences of the era's most volatile ideological conflicts.
