Why You'll Love This

Over ten thousand women helped crack the codes that shortened World War II — and almost none of them were ever allowed to tell anyone.

  • Great if you want: untold WWII history centered on overlooked women's intellectual contributions
  • The experience: methodical and absorbing — dense with detail but consistently rewarding
  • The writing: Mundy weaves personal portraits into big history, making statistics feel human
  • Skip if: you prefer narrative momentum over deep archival depth

About This Book

During World War II, more than ten thousand American women quietly helped win the war — not on the battlefield, but in Washington offices, hunched over coded enemy transmissions. Recruited from colleges and small towns, sworn to secrecy, these women cracked Axis codes that altered the course of history, then came home and said nothing for decades. Liza Mundy recovers their story with the urgency it deserves, capturing not just the intellectual feat but the human one: young women stepping into a world that had never quite made room for them, doing extraordinary work, and being asked to disappear back into ordinary lives when it was over.

What makes this book worth the investment of its considerable length is Mundy's skill at keeping individuals vivid inside a sweeping collective story. She draws on declassified documents and first-person interviews to move between the intimate and the historical — you follow specific women through their fears, friendships, and breakthroughs while never losing sight of the larger stakes. The prose is clear and propulsive, and Mundy resists both sentimentality and hagiography, letting the facts carry the emotional weight on their own.
