Summary

The narrator becomes the biographer of Francis Blundy’s unread poem Corona, first recited at a dinner in 2014. He documents its early mentions: a letter by Harry Kitchener, a blog, an article by “Jane Smith,” and Harriet Gage’s 2017 Guardian piece linking the poem to Derangement. After Blundy’s death, conspiracy theories claim fossil‑fuel interests suppressed the poem. In 2021, the narrator discovers a protest placard reading “Blundy Spoke True” in a student’s essay, leading him to hundreds of online references. The poem is later co‑opted by relationship communities as a manifesto for long love. The chapter recounts escalating global crises: nuclear exchanges between India‑Pakistan and in the Middle East, the Inundation of 2042, and the subsequent cooling that sparks an ecological revival. The Corona becomes a symbol of lost nature, inspiring competitions to recreate it. The narrator concludes that the imagined poem holds more power than any actual text, serving as a talisman for survivors in the twenty‑second century.

Key Events

  • The narrator outlines the Corona’s trajectory from its 2014 recital through various media and conspiracy theories.
  • In 2021, a student’s essay includes a photograph of a protester with the placard “Blundy Spoke True,” prompting the narrator’s deep search.
  • Online references to Blundy explode from 107 mentions (2018–2020) to 678 (2021–2025).
  • The poem is appropriated by relationship websites as an emblem of enduring love.
  • The climate‑change movement declines due to Derangement and global tensions.
  • The first climate war (2036) between India and Pakistan involves limited nuclear exchanges.
  • Saudi Arabia and Israel invade Iran, resulting in battlefield nuclear explosions.
  • A Chinese‑US naval clash in the Taiwan Straits leads to a sunken carrier.
  • The Inundation of 2042: a Russian H‑bomb accidentally triggers a megatsunami, killing over 200 million and destroying coastal cities.
  • Post‑nuclear cooling lowers global temperatures by nearly two degrees, sparking a “climate opportunity” and renewed ecological longing.
  • The Corona is reinterpreted as a hymn to nature; poetry competitions attempt to reconstruct it.
  • The narrator reflects that the imagined poem is more powerful than any recovered original.

Character Development

  • Narrator (the biographer) – Reveals his hands‑on research method; his skepticism about the poem’s actual quality; he becomes a historian of cultural reception.
  • Rose – The narrator’s wife and a professor; she encourages the student project that leads to the key discovery.
  • Michelle – A shy student whose essay contains the crucial placard photograph; her work is otherwise unremarkable.
  • Vivien Blundy – The poet’s widow; she is upset by public portrayals of her marriage and tries to suppress the poem.

Themes, Symbols, or Motifs

  • The unread masterpiece – The Corona exerts influence precisely because it remains unknown; its meaning is projected by different groups (climate activists, romantics, nature lovers).
  • Global catastrophe and human resilience – Nuclear wars and the Inundation ironically lead to climatic cooling, giving humanity a second chance that is only partially realized.
  • The imagined versus the actual – The narrator argues that imagined ideals (God, fiction, the poem) hold more sway than concrete realities; the Corona is “more beautiful for not being known.”
  • Biophilia – The revived longing for the natural world after disaster frames the poem as a symbol of lost ecology.
  • Plato’s cave – The narrator alludes to the shadow‑play of forms, suggesting that the Corona exists as an unattainable ideal.

Why This Chapter Matters

This chapter expands the story from a single poem’s reputation to a sweeping history of the twenty‑first and twenty‑second centuries. It shows how a cultural artifact can be repurposed across vastly different contexts—from climate activism to romance—while remaining unknown. The narrator’s account of nuclear wars and the Inundation grounds the novel’s speculative future in stark consequences of the Derangement. The chapter also crystallizes the book’s central epistemological question: how we “know” something that is absent, and how that knowledge shapes belief and action. The Corona becomes a cipher for human longing, making this chapter a meditation on the power of absence.

Study Questions and Answers

  1. What event in 2021 led the narrator to discover evidence of the Corona’s influence?
    The narrator was marking a student’s project on Derangement protests. The essay, written by Michelle, included a photograph of a teenage boy holding a placard reading “Blundy Spoke True.” This image prompted the narrator to search activist websites, where he found hundreds of references to Blundy’s poem.

  2. How did the Inundation of 2042 affect the planet’s climate and the Corona’s meaning?
    The Inundation, triggered by a misdirected hydrogen bomb, killed over 200 million people. The resulting dust and sand in the upper atmosphere caused global temperatures to drop by nearly two degrees. This cooling, combined with trauma, revived ecological movements. The Corona was then reinterpreted as a hymn to lost nature, and competitions to recreate the poem emerged.

  3. What does the narrator conclude about the value of an unread poem?
    The narrator argues that the imagined poem is more powerful than any actual recovered text. He draws parallels with religious believers who do not want God depicted, and with our comfort in not understanding how machines work. For the narrator, the Corona has served history well by remaining a blank sheet, a talisman that promises a better future without being pinned down.
