Gather initial thoughts and broad opinions about the book.

• Kate Quinn has written several novels set before, during, and after World War II, such as The Alice Network, The Huntress, and The Diamond Eye. How does this novel compare with Quinn’s other work set in this era? How does the perspective of this novel differ from the others?
• Had you heard about the Bletchley Park codebreakers before reading this novel? What else did you know about World War II-era codebreaking before reading this? How did your knowledge and perception of codebreaking in this era influence your reading?

2. Personal Reflection and Connection 

Encourage readers to connect the book’s themes and characters with their personal experiences.

• The novel’s three protagonists are Osla, Mab, and Beth. Whose story and personality do you relate to most and why?
• Osla, Mab, and Beth’s friendship goes through ups and downs. Does this resonate with you when it comes to your own friendships and relationships?
• At a crucial point in the novel, Beth’s decision not to break the Official Secrets Act indirectly leads to the death of two of Mab’s loved ones. This creates a rift between the women.
