Summary

One year after the events on Capri, Hannah narrates from Paris, where she, Lainey, and Tyson are on a long‑awaited trip. The three have been training for the Chicago Marathon as part of #TeamSummer, a tribute team organized by Summer’s brother to raise money for the American Foundation for Suicide Prevention. Lainey, now nine months sober after attending rehab in Antigua, reflects on her recovery journey. Hannah describes her own transformation: she left Atlanta after her ex Grady began dating Berlin, moved to Austin, took a job with a boutique design firm, and started a master’s program in interior design. She is in a relationship with Olivia, whom she met after Capri. The chapter culminates at the Trocadéro fountain, where Tyson reveals the original Summer Pact paper with a new line: “Will you marry me?” He proposes to Lainey, who accepts. The four friends—Hannah, Lainey, Tyson, and Olivia—celebrate together, feeling Summer’s presence and affirming that their friendship and risks have led them to happiness.

Character Development

  • Hannah – Shows the greatest growth by leaving her controlling mother and the painful social web of Atlanta. She follows her heart to Austin, pursues a design career, and embraces a relationship with Olivia without seeking approval. Her fear of losing her friends is tempered by a new willingness to take risks.
  • Lainey – Demonstrates sustained recovery and vulnerability. Her sobriety journey, acknowledged as harder than a marathon, reshapes her identity. The proposal scene reveals her enduring theatrical flair (“follow me on Instagram!”) but now rooted in genuine joy rather than escapism.
  • Tyson – Evolves from a critical friend into a supportive partner. He convincingly pushed Lainey toward sobriety and now commits to moving to New York for her. His proposal uses the group’s pact as a symbol of enduring connection.
  • Olivia – Though not a main narrator, her presence confirms Hannah’s new life. She is fully accepted by the friend group, and her surprise arrival underscores the theme of chosen family.

Themes, Symbols, or Motifs

  • The Summer Pact – The physical paper evolves from a spur‑of‑the‑moment promise into a living document that anchors a marriage proposal. It symbolizes loyalty, growth, and the group’s ability to keep their word.
  • Running as metaphor – Training for a marathon represents discipline, endurance, and honoring Summer. The slow pace mirrors the friends’ gradual but steady progress toward healing.
  • Sobriety and recovery – Lainey’s nine‑month medallion and her commitment to AA meetings illustrate the ongoing work of rebuilding a life. The chapter reframes addiction as a treatable symptom, not a moral failing.
  • Chosen family – Hannah explicitly calls Lainey, Tyson, and now Olivia her “chosen family.” The group’s solidarity replaces broken biological ties (Hannah’s mother, Lainey’s unspecified family).
  • Grief transformed into purpose – #TeamSummer channels loss into athletic and fundraising achievement. The friends feel Summer’s presence throughout the celebration.

Why This Chapter Matters

Chapter 37 serves as the emotional and structural resolution of The Summer Pact. It answers each character’s arc: Hannah breaks free from her past, Lainey achieves sustainable sobriety, Tyson matures into a committed partner, and the group’s bond strengthens rather than fractures after tragedy. The proposal at the Trocadéro, using the pact as a prompt, ties the novel’s central symbol to a new commitment. The chapter also validates the risk of love and friendship, urging readers to live “in a small, fear‑based way” no longer. It leaves the quartet unified, acknowledging that while life will never be perfect, showing up for one another is enough.

Study Questions and Answers

  1. Question: How does the Chicago Marathon tribute team reflect the friends’ growth from the summer pact?
    Answer: The marathon, organized by Summer’s brother for the American Foundation for Suicide Prevention, transforms their grief into action. Training requires the same perseverance and mutual support that defined their original pact. Lainey and Hannah initially doubted they could run 26.2 miles, but Tyson’s encouragement—comparing the challenge to Lainey’s sobriety—pushes them to commit.

  2. Question: What does Hannah mean when she says she’s “not living my life for my mother” and also “not rebelling against her”?
    Answer: Hannah describes a form of emotional independence. In the past, her choices (like her relationship with Grady) were either dictated by her mother’s expectations or a direct reaction against them. Now, in moving to Austin, pursuing interior design, and dating Olivia, she acts solely on her own desires. Her mother’s opinion no longer factors in, which is a mature departure from both compliance and rebellion.

  3. Question: Why does Tyson choose the Summer Pact paper for his proposal?
    Answer: The pact represents the foundation of the three friends’ loyalty. By adding “Will you marry me?” below their original signatures, Tyson demonstrates that his commitment to Lainey is an extension of that original promise. The physical document ties their romantic future to the friendship that saved them after Summer’s death, making Lainey’s acceptance a renewal of their bond.
