The Mitford Affair is a historical novel told through the alternating perspectives of Nancy, Diana, and Unity Mitford—three sisters caught in the rising tide of fascism between the World Wars. As Britain staggers through economic crisis and social upheaval, Diana abandons her privileged marriage for British fascist leader Oswald Mosley, while Unity fixates on Adolf Hitler with frightening devotion. Nancy, the novelist with the cutting tongue, watches her family fracture as politics becomes painfully personal.
Over the decade leading to World War II, the sisters’ choices draw them into rallies, scandals, and Nazi inner circles—until violence, betrayals, and a devastating act of self-harm force Nancy to confront a question she can’t evade: when does love for family become complicity? The story follows the Mitfords from London drawing rooms to Munich restaurants and finally into the moral reckoning of war.
