This memoir is based on notes that the author, E.B. Sledge, kept tucked away in a pocket-sized Bible he carried with him during battles he fought at Peleliu and Okinawa.

(From the book jacket):  Recruited from small Southern towns and posh New England colleges, 10,000 American women served the U.S. Army and Navy as code breakers during Wold War II.  Their code-breaking triumphs shortened the war, saved countless lives, and gave them access to careers previously denied to them.
