The Postmistress is a story about two women during WWII before the US gets involved. Frankie is a war correspondent in London and Iris is the postmaster in a small town in Cape Cod. It’s a time when mail was an important way of communicating around the world. Frankie sees all the horrors of war in Europe while Iris listens to her radio broadcasts and waits for the US to decide when to send troops. They eventually meet in Cape Cod and both have a secret they have been keeping. It’s a sad book but that’s how most war stories are.
