Gather initial thoughts and broad opinions about the book.

1. What was your overall reaction to the novel’s structure, which alternates between Carrie’s passionate 2010 romance with Johan and her settled 2022 life in Devon? Did the back-and-forth between timelines pull you deeper into the story, or did you find it disorienting at times? How did that experience shape the way you understood Carrie’s emotional state?

2. Rosie Walsh builds the novel around the idea that lies told in the name of protection can cause more lasting harm than the truths they conceal. How convincing did you find this argument as it plays out across the novel? Were there moments where you felt a character’s deception was understandable, or did the cumulative weight of the secrets make it difficult to sympathize with anyone who withheld the truth from Carrie?

3. The One Day You Were My Husband centers on the sudden reappearance of a past love who was believed lost forever. If you’ve read other novels that explore this kind of reunion across years of separation, such as Jojo Moyes’s Me Before You or any other romance that hinges on unfinished emotional business, how does the novel compare in the way it handles the tension between what was and what is?

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

1. Carrie describes her method of healing after the trauma in Thailand as a structured formula, approaching her grief the way a surgeon might approach a medical problem. Think about how you’ve processed a significant loss or disruption in your own life. Did you rely on structure and routine the way Carrie does, or did you find a completely different path through it?

2. Maya and Carrie have a relationship built on contrast: one is cautious and rule-following, the other impulsive and emotionally driven. Yet Maya’s instincts consistently push Carrie toward confronting what she’d rather avoid. Think about a relationship in your own life, whether a sibling, friend, or colleague, where someone’s very different way of moving through the world ended up being exactly what you needed. What did that dynamic teach you?

3. Carrie’s surgical career represents her sense of identity and control, so its absence leaves a deep gap in who she understands herself to be. Have you ever stepped away from work, a creative pursuit, or a role that felt central to your sense of self? How did that absence change the way you related to your own life, and what did it feel like to return, or imagine returning?

4. Throughout the novel, characters make decisions on Carrie’s behalf under the belief that they’re keeping her safe, and these choices consistently deny her the information she needs to shape her own life. Have you ever found yourself in a situation where someone withheld something from you out of a desire to protect you? Looking back, how did you feel about their reasoning once you learned the full picture?

5. Johan and Robin represent two very different models of partnership for Carrie: one built on electric, mutual recognition, and the other on security and steadiness. Considering your own understanding of what makes a relationship feel solid, which of those qualities do you think is harder to sustain over time, and why?

Examine the book’s relevance to societal issues, historical events, or cultural themes.

1. Johan’s imprisonment is directly shaped by Thailand’s 2003 war on drugs, a campaign in which thousands of people were killed, many with no proven connection to drug activity. The novel shows how an individual’s fate can be decided not by the facts of their case but by the political climate surrounding it. What does this historical backdrop add to your understanding of Johan’s choices inside the prison, particularly his decision to plead guilty and push Carrie away?

2. Yanika warns Carrie that surgery is still a profession that has not made room for women who prioritize their children. How does this reflect broader patterns you see in demanding fields today? Do you think the novel offers a realistic picture of what it costs women to re-enter high-stakes careers after time away, or does its resolution feel more aspirational than true to life?

3. The novel traces a web of criminal activity that reaches from a Myanmar diving expedition to a London charity gala and eventually into Carrie’s own home. Robin’s employer, Valentin Meyer, runs what the novel describes as a reputation-laundering operation, using philanthropic work as a cover for criminal enterprise. What does the story suggest about the way wealth and charitable prestige can obscure wrongdoing, and how does Carrie’s own position, financially dependent on Robin and insulated from his professional life, make her particularly vulnerable to this kind of hidden corruption?

Dive into the book’s structure, characters, themes, and symbolism.

1. The squid boats first appear as a serene image on the night of Carrie and Johan’s wedding, but Carrie later discovers their true function: They use bright lights to attract and capture prey. How does this shift in meaning reflect the novel’s broader argument about the gap between how things appear and what they actually are? Which other details in the story undergo a similar transformation once the full truth emerges?

2. Robin’s passion for astronomy is presented as evidence of his thoughtful, truth-seeking character, and yet his final lie to Carrie is that he has taken the children to an astronomy event. How does Walsh use this motif to develop his character across the novel? What does it mean that the very symbol of his credibility becomes the instrument of his exposure?

3. Johan and Robin function as deliberate foils throughout the narrative. Considering their professions, their hobbies, and the way each one relates to Carrie’s autonomy, what does the contrast between them suggest about the novel’s definition of what genuine care for another person actually looks like?

4. How does the novel use humor during moments of fear, grief, or emotional confrontation? What does the movement between comedy and seriousness reveal about the relationships among the characters?

5. Walsh structures the novel so that Carrie’s domestic life unravels at exactly the moment she begins to reclaim her professional one, and these two movements, return to surgery and collapse of her marriage, are inseparable in the plot. How does this structural choice reinforce the novel’s treatment of the tension between parenthood and professional ambition? Does the resolution feel like a genuine integration of these two parts of Carrie’s life, or a compromise?

6. Adelina’s character shifts meaning several times across the novel, from devoted if overbearing mother, to unwitting catalyst for disaster, to secret architect of Johan’s freedom. How does Walsh use the technique of withheld information to control how readers judge her? At what point, if any, did your reading of Adelina change most significantly, and what triggered that shift?

Encourage imaginative and creative connections to the book.

1. Imagine you’re writing the scene where Adelina finally tells Carrie the full truth about her role in Johan’s arrest and her years-long effort to secure his pardon, a conversation that never happens on the page. What does Adelina say first? Does she lead with the apology, the explanation, or the confession, and how does Carrie respond in the moment before the anger arrives?

2. The novel ends with Carrie driving to Johan’s seaside cabin to tell him she loves him and is ready for a future together. If you were to write a short scene set five years after that ending, what would their life look like? What challenges would they still be navigating, and what would feel, finally, settled?

3. Think about the role the Roof rental app plays in the novel: It’s the platform that first reveals Johan is alive, the medium through which Maya accidentally sends a booking request, and the space where Johan sends and then deletes his message to Carrie. If you were adapting this story for a film or television series, how would you translate these digital moments to the screen in a way that captures their emotional weight without losing the audience in the mechanics of an app?
