We first meet Anna Kerrigan when she is 11 years old, when she accompanies her father Eddie on a work visit to Dexter Styles at his wealthy home near Manhattan Beach. Anna understands that this man is possibly a gangster, and she is fascinated by his home, his children, and the mystery of how her father is connected to Dexter.
Years later, the country is at war, and her father has disappeared. Anna is working at the Brooklyn Navy yard, and eventually becomes the first woman diver, fixing ships below the water. She encounters Styles again at a nightclub he owns, and their lives become intertwined in unexpected ways.
This is an immensely satisfying historical novel.
