I absolutely loved this book. It was my first read by Kate Quinn, and it absolutely will not be my last. I enjoy historical fiction that fictionalises real life people as well as eras and events in history, and this book loosely bases one of the main characters on Osla Benning, a socialite who was actually Prince Phillip’s wartime girlfriend, and worked at Bletchley Park. The comradeship between the women, the peril of wartime and the secrecy of BP comes through so well. I found myself sailing through the pages, and reading well beyond when I should have been fast asleep!
