Chapter 29 – Jess’s Diary: The Truth Comes Out

⚠️ 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

Jess records a diary entry dated 10 January 1999. She suffers severe nightmares and sleepwalks to the bathroom, where she turns on the tap and watches the webbed flesh between her toes shed to reveal a shining blue layer underneath. She realises that she was found abandoned by the sea and that her adoptive parents, Robert and Judith Wilson, moved her to Dawes Plain—nearly 1,000 kilometres inland—to keep her from water. Determined to learn more, Jess lies to her mother and cycles to school. There she meets her art teacher, Mr Hennessey, and confesses everything: that the people she calls Mum and Dad are not her biological parents, that her true home is Cliff House in Comber Bay, and that she is drawn to water. Mr Hennessey listens without judgement, shares a personal story about his father’s bigotry, and promises he will not hurt her. They share a moment of physical intimacy—holding hands and, later, an implied sexual encounter. Before leaving, he gives her a borrowed book, A Wave of Dreams by Louis Aragon, which speaks to dreams as communing with ghosts. Jess feels seen and understood for the first time.

Character Development

Jess: Moves from shame and avoidance (refusing to see Max, hiding from her parents) to active truth-seeking. She sheds not only her skin but also her old identity, deciding to show herself without concealment. Her trust in Mr Hennessey signals a turning point in her isolation.
Mr Hennessey: Reveals a vulnerable past (his father’s homophobia) and becomes a confidant. His careful listening and gift of the book show his empathy and his willingness to bridge the gap between teacher and student.
Robert and Judith Wilson: Remain off‑page, but Jess’s view of them shifts from “stranger” to “liars,” deepening the generational and emotional fissure.

Themes, Symbols, or Motifs

Transformation and Shedding: The physical shedding of webbed skin mirrors Jess’s psychological shedding of her false life. She compares herself to a snake, “new and perfect and free.”
Water and Belonging: Water is both a threat (the nightmares, the tap) and a source of identity (the imagined salt rush of the sea). Jess’s longing for the sea represents her quest for authentic selfhood.
Art as Understanding: Mr Hennessey’s love of art—and his sharing of Aragon’s book—becomes a medium for emotional connection. The book’s theme of dreaming as “communing with ghosts” parallels Jess’s own hauntings and her desire to reunite with her hidden past.
Secrecy and Revelation: The chapter contrasts lies told to parents (the swimming lie) with the raw truth Jess offers Mr Hennessey. The moment of hand‑holding breaks a spell of isolation.

Why This Chapter Matters

This chapter is the emotional and narrative pivot of Jess’s arc. She stops hiding and actively seeks the truth about her origins. Her confession to Mr Hennessey—and his acceptance—provides the first genuine human connection she has experienced since her adoption fell apart. The imagery of shedding skin and the gift of the book cement her transformation from a girl ashamed of her difference to one who embraces it. The chapter also deepens the novel’s central mystery by confirming that Jess is not a normal human, that her parents were deliberately keeping her from water, and that her dreams are tied to a real place (Comber Bay). It sets up the next stage of her journey: returning to the sea.

Study Questions and Answers

1. Why does Jess lie to her mother about going to the reservoir with Max?
She wants to go to school alone to meet Mr Hennessey without her parents’ knowledge. The lie also conceals her growing estrangement from Max after their awkward sexual encounter.

2. How does Mr Hennessey respond when Jess tells him her parents are not her biological parents?
He listens carefully, does not interrupt, and then shares his own experience of discovering his father was a bigot. He reassures her that not everyone will hurt her and lets her take the lead physically, showing trust and respect.

3. What does the book A Wave of Dreams symbolise in this chapter?
It represents Mr Hennessey’s understanding of Jess’s inner life—especially her dreams and her sense of being haunted. By giving it to her, he offers a tangible connection between them, and Jess’s act of sleeping with it under her pillow indicates that it becomes a surrogate for his presence.
