⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
The chapter opens in late autumn, nearly winter, as Cassie returns from a walk to find Mr. Webber in a state of barely contained excitement. He announces that he has found the Book of Doors. Since witnessing the younger version of Cassie, Mr. Webber has been actively searching for the book, sending emails to his network of rare book collectors describing it as Cassie had described it to him—without revealing anything about its magical properties.
His contact Morgenstern, a collector in Toronto, replied claiming he found a book matching the description during a holiday in Eastern Europe, specifically Romania. Mr. Webber shows Cassie photographs of the book, and although the images lack resolution to confirm the details, Cassie's heart leaps with hope. It might be the Book of Doors.
Mr. Webber arranges for Morgenstern to fly to Manhattan that evening, covering his travel and hotel expenses. Cassie, who has been stranded in time for over four years, immediately begins planning. She hopes that if she obtains the book, she can travel back earlier and rescue Izzy from the apartment before Hugo Barbary arrives.
Before they leave, Mr. Webber expresses his sadness, admitting he will miss Cassie if she goes home. The two share a tender moment, with Cassie hugging him from behind and promising they will meet again.
They meet Morgenstern at the Champagne Bar in the Plaza Hotel. Morgenstern is theatrical and self-important, dressed in an expensive suit with a cravat. He is dismissive of Cassie, referring to her as "this girl" and treating her with barely concealed condescension. Mr. Webber introduces her as his research assistant, Ms. Andrews, and gently admonishes Morgenstern for his rudeness.
The package sits on the table, wrapped in brown paper, roughly the size of the Book of Doors. Morgenstern delays the reveal, ordering champagne and drawing out the moment. Cassie, desperate, finally tears the paper off the book herself. The leather cover and spine look like the Book of Doors, and her heart races.
But when she opens it, she finds text in a European language—possibly Romanian—written by a human hand. There are no indecipherable scribbles, no sketches. It is not the Book of Doors. The disappointment is devastating, opening a vast chasm in front of her. Tears fill her eyes as she shakes her head at Mr. Webber.
It takes Cassie days to recover from the disappointment. Mr. Webber apologizes repeatedly, but Cassie waves it away, telling him he gave her hope for a few hours, which was nice. She acknowledges the devastation but says it made her realize how much she wants to get home and that she needs to start thinking about that.
She reveals an idea she had weeks earlier—a memory of something Drummond Fox said to her. It is not a way to find the Book of Doors, but rather a plan to prepare herself for the dangers waiting in her present. Over the following months, she investigates this idea, looking for a person rather than a book. It takes almost six months to make contact, then several more months of cautious discussion between two people figuring each other out. She tests her thoughts with Mr. Webber throughout.
Almost a year after her epiphany in Bryant Park—nearly five years after arriving in the past—Cassie takes a long journey alone. She has a meeting, a discussion, and makes a deal. When she returns to New York, Mr. Webber asks how it went. She nods and says it is done; now they just have to wait.

Character Development
Cassie undergoes significant emotional movement in this chapter. Her initial hope is palpable—she has been stranded in time for over four years, and the prospect of returning home and rescuing Izzy before Hugo Barbary arrives consumes her. The false hope is devastating, but it crystallizes her determination. Rather than remaining passive, she pivots from searching for the book to preparing for the dangers ahead, demonstrating resilience and strategic thinking. Her decision to act on a memory of Drummond Fox's words shows she is learning to use the knowledge she has accumulated.
Mr. Webber reveals a deeper emotional attachment to Cassie than previously shown. His admission that he will miss her, and his embarrassment at showing his upset, humanize him. His repeated apologies after the failed book reveal show his care for her wellbeing, even as Cassie insists he has nothing to apologize for.
Morgenstern is introduced as a self-important, theatrical collector who enjoys the finer things in life. His dismissive treatment of Cassie and his drawn-out reveal of the book paint him as a minor antagonist, though not a villain—merely a man enjoying his moment of importance.
Themes, Symbols, or Motifs
False hope and the cost of hope. The chapter's central emotional arc is the rise and fall of hope. Cassie's hope is so powerful that it makes her heart leap, and its collapse is correspondingly devastating. Cassie's reflection that Mr. Webber gave her hope for a few hours, and that this was nice, suggests that hope has value even when it ends in disappointment—but the chapter also shows its cost.
Resilience and preparation. Cassie's recovery from disappointment is not passive. She transforms her pain into action, developing a plan to prepare for future dangers. The chapter emphasizes that preparation—investigating, making contact, building trust over months—is a different kind of hope, one grounded in action rather than wishful thinking.
Time displacement and the search for home. Cassie's four-plus years stranded in the past frame her desperation. The Book of Doors represents not just a magical object but the possibility of returning home and undoing past harm. The false lead underscores how elusive that possibility remains.
Strategic deal-making. The chapter ends with Cassie completing a deal after months of cautious negotiation. This mirrors the novel's broader themes of exchange, trust, and the careful building of relationships as a form of power.
Why This Chapter Matters
This chapter marks a turning point in Cassie's approach. The false lead forces her to abandon passive hope in favor of active preparation. Her pivot from searching for the Book of Doors to preparing for the dangers of her present suggests a new phase in her journey—one where she is no longer merely surviving in the past but strategically positioning herself for what lies ahead. The chapter also deepens the relationship between Cassie and Mr. Webber, and the closing note—"now we just have to wait"—sets up anticipation for what her deal will bring.
Study Questions and Answers
1. Why does Cassie react so strongly to the false book, and what does this reveal about her state of mind after four years in the past?
Cassie's reaction—tears, devastation, days of low mood—reflects the accumulated weight of over four years stranded in time. The book represented not just a magical object but the possibility of returning home and rescuing Izzy before Hugo Barbary arrives. The false lead collapses that hope in an instant, and the intensity of her reaction shows how much she has been holding onto this possibility. Her recovery, however, reveals her resilience: she transforms the disappointment into determination to prepare for the dangers ahead.
2. How does Mr. Webber's behavior in this chapter deepen our understanding of his relationship with Cassie?
Mr. Webber's excitement at finding the book, his sadness at the prospect of Cassie leaving, and his repeated apologies after the false lead all reveal a genuine emotional attachment. His admission that he will miss her, and his retreat to his bedroom to hide his upset, show vulnerability beneath his bookish exterior. Cassie's response—hugging him and promising they will meet again—suggests a mutual affection that has grown over their years together.
3. What does Cassie's pivot from searching for the book to preparing for danger suggest about her character growth?
Cassie's decision to act on a memory of something Drummond Fox said, and her months-long process of investigating, making contact, and completing a deal, show a shift from reactive hope to strategic action. She is no longer waiting for the Book of Doors to save her; she is building the means to face the dangers waiting in her present. This suggests she has learned that preparation and relationships are forms of power, and that she is becoming more proactive in shaping her own fate.
