1940, London

When Cordelia accepts the post of head librarian in Silver Town Library, her mother is more than a little disapproving. The East End has high levels of poverty and illiteracy, and her mother says it's no place for a woman of her status.

But Cordelia is determined to make a difference in these times of strife, and along with her colleagues, Jane and Mavis, she begins to help the local community, making sure everyone knows what the library can offer them.

And maybe even a romance will blossom, giving Cordelia the strength to make it through the chaos and destruction that constantly threatens their livelihood.

Against a background of war, air raids and rationing, it becomes clear the library is more than a building filled with books - it is the beating heart of a community refusing to be torn apart.
