⚠️ 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

Chapter 17 is presented entirely as Jo’s diary, dated April 13 and April 15, 2006. Jo has brought her daughter Bridge to New Orleans under the pretext of a vacation, but her real purpose is to confirm that the events of her past – especially the dreamworm and her encounter with another version of herself, Jo‑Anne – were real. She fears that the brain tumor that struck her as a teenager has returned, but doctors dismiss her symptoms as stress or anxiety. Her husband Dave belittles her fears and controls her finances and decisions.

Jo visits the dilapidated warehouse Leftfield, the commune where she lived as a runaway. She then meets Mina Remington, an old friend and former Leftfielder, who gives Jo a dwindled dreamworm cocoon that Rabbit once created. Jo believes that by using the cocoon she can travel to another version of herself – a smarter, healthier self – who may have found a cure for cancer. Despite Mina’s warnings about the danger, Jo takes the cocoon, feeling she has no other choice.

Character Development

Jo: This chapter deepens Jo’s desperation and courage. She is no longer passive; she takes decisive action to find a cure, even at great risk. Her diary voice shows self‑awareness of her own failings, her regrets about leaving Leftfield, and the painful cost of her marriage. She is determined to live for Bridge, yet she also admits she cannot continue living with Dave.
Bridge: Bridge is a child, scared and needy, but also curious. She provides an emotional anchor for Jo, grounding her in the present. Her reactions – gasping at the naked model, tugging Jo to leave Leftfield – highlight the tension between Jo’s mission and Bridge’s safety.
Dave: Though absent, Dave looms large. Jo’s diary reveals his gaslighting, financial control, and emotional cruelty. He dismisses her epilepsy and tumor fears, calls her “fragile,” and demands she be a full‑time mother. He is a symbol of domestic imprisonment.
Mina Remington: Mina is a complex survivor – clean for two years but still haunted. She is both supportive and wary, willing to help Jo but clearly afraid of the cocoon’s power. Her own infertility and failed marriage mirror Jo’s struggles, and she serves as a cautionary figure.
Rabbit (mentioned): Rabbit is dead, probably murdered. He made the cocoon and was paranoid about being followed. His fate underscores the danger surrounding the dreamworm.

Themes, Symbols, or Motifs

Memory and the Past: Jo’s diary is an act of excavation. She returns to Leftfield to verify her memories, and the ruined building becomes a physical manifestation of the “imaginary country” of the past. The buried railway tracks and the ghost of the rabbit symbolize inescapable history.
Control and Gaslighting: Dave’s control over Jo’s body, finances, and identity is a form of psychological imprisonment. Jo likens it to “cotton wool” – a prison of soft suffocation. The theme contrasts with Jo’s teenage rebellion, when she was free but vulnerable.
Motherhood and Sacrifice: Jo’s mantra “Your child needs you” drives her, but motherhood also closes doors. She gave up her studies and career. Bridge is both her reason to live and the chain that holds her to a destructive marriage.
The Artichoke as a Symbol of Potential: Mina’s artichoke – closed and spiky, then opening into star‑like seeds in sunlight – represents the idea of blooming under the right conditions. It parallels Jo’s hope that a better version of herself exists somewhere.
The Cocoon as Hope and Danger: The dreamworm cocoon is a physical object of immense potential, but also of risk. It has shrunk, suggesting its power may be waning, and Rabbit’s death hints at its lethality. Jo’s choice to take it despite unknown consequences embodies the theme of risk for survival.

Why This Chapter Matters

Chapter 17 is a turning point for Jo’s story. It transitions her from passive victim of her illness and marriage to an active agent who reclaims her past and seeks a radical cure. The diary format gives intimate access to her thoughts and history, building empathy for her desperation. It also reveals the origin of the cocoon and the danger surrounding it, raising the stakes for Bridge and the larger narrative. The chapter ends with a cliffhanger: Jo has the cocoon, but using it may be perilous – both for her and for Bridge.

Study Questions & Answers

1. Why does Jo go to New Orleans, and what does she hope to find?
Jo goes to New Orleans under the guise of a vacation, but her real goal is to confirm that her past at Leftfield and her encounter with the dreamworm were real. She hopes to find the cocoon that Rabbit made, which she believes will allow her to travel to another version of herself who has found a cure for her brain tumor.

2. How does Jo’s husband Dave contribute to her sense of helplessness?
Dave dismisses Jo’s fears of cancer, calls her “obsessive paranoia,” and refuses to pay for further medical tests or therapy. He controls their finances, belittles her ambition to return to neuroscience, and uses emotional manipulation – telling her to “grow up” and focus on their child. His control, while not physically violent, traps Jo in a “cotton wool prison.”

3. What does the artichoke symbolize in Mina’s studio, and how does it relate to Jo’s journey?
Mina’s artichoke, when brought into sunlight, opens its closed spines into fine, star‑like seeds. It symbolizes hidden potential and the need for the right conditions to bloom. For Jo, it reinforces her belief that a better version of herself exists – one who is healthy and free. It also connects to Mina’s advice to “find people that are like sunlight for you,” which Jo is now doing by reconnecting with her past.
