Chapter 7 Summary and Analysis

⚠️ 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

On the morning of June 17, 2019, Jax begins cleaning the kitchen at Sparrow Crest. The bright daylight makes her midnight fears seem foolish, but she quickly discovers unsettling details: the kitchen lights are out because the bulbs are missing, and the Dutch door leading to the patio has been sealed shut with metal brackets. The fridge holds only spoiled food and a shopping list that includes odd items like “long nails and screws” and a note to ask Bill about a night vision camera. A wall calendar reveals that Lexie had dinner with Ryan, a fact Jax didn't know. This triggers a childhood memory of Lexie chasing a peacock through the woods, with Ryan offering to help her catch it.

While sweeping, Jax finds a notebook paper under the table with the words “Something’s in the water.” She pulls the curtain closed to avoid looking at the pool. Moving to the living room, she finds more missing and smashed light bulbs, scattered family photos, and piles of papers. She begins to sort through Lexie’s notes, which contain coded entries like “F6: 6/9 11:05 p.m.—over 50 meters!” and “They don’t like the light.” One entry dated June 12 insists, “I know what I saw. I am not crazy. This was no hallucination. I think it came out of the water.” Another pink note reads, “She isn’t who she says she is.”

Jax also discovers Lexie’s extensive research on the property’s history: surveys, tax records, maps of Brandenburg from 1865 and 1929, and a local history book. In that book, Lexie underlined a passage about the first settlers finding a carved rock at the spring with the words “prendre garde,” meaning “beware.”

Finally, Jax forces herself to go outside to the pool. She recalls Gram’s stories about the spring’s healing and magical properties, as well as warnings that the water is cursed and demands a price for miracles. She remembers Lexie’s childhood obsession with diving to the bottom of the supposedly bottomless pool. Now, she sees that Lexie had created a grid of letters and numbers on the stones around the pool, and a weighted measuring tape up to 50 meters, suggesting she was trying to measure the pool’s depth.

Jax receives a call from Karen, a social worker covering her clients. Karen reports that Declan, one of Jax’s young clients, threw bleach into a fish tank at school and injured his teacher. Jax feels guilty for not returning his call. After hanging up, she notices a paper boat floating in the pool. She retrieves it and unfolds it to find a message in Lexie’s handwriting: “Why didn’t you pick up the phone?” Jax drops the paper back into the water and, for a moment, thinks she sees a shadow moving beneath the surface.

Character Development

Jax is overwhelmed by guilt and grief. She repeatedly blames herself for not answering Lexie’s calls, and the same guilt resurfaces when she learns she missed Declan’s call. Her initial dismissal of her nighttime fears gives way to a growing unease as she pieces together Lexie’s obsessive behavior. She is also forced to confront her own childhood memories—both the magical belief in the pool’s power and the “terrible thing” she once wished for. Her decision to finally approach the pool shows her trying to face the reality of her sister’s death, but the final shadow suggests she is not ready to accept a rational explanation.

Lexie is revealed through her notes and actions as deeply troubled and possibly manic. Her coded measurements, her insistence on seeing something emerge from the water, and her fixation on light and darkness all point to a mind consumed by the mystery of the pool. The note “She isn’t who she says she is” hints at paranoia or a specific suspicion. Her research into the property’s history shows a desperate attempt to understand the spring’s power, and her paper boat message to Jax reveals a longing for connection that went unanswered.

Declan, though off-page, mirrors Lexie’s obsession with transformation and hidden identities. His nightmare fish and his violent act of pouring bleach into a tank echo Lexie’s own fears about things that “aren’t who they say they are,” creating a parallel between the two characters.

Themes, Symbols, or Motifs

Water as Healing and Cursed: The pool is described as having magical properties, but also as demanding a price for miracles. Gram’s stories and the historical warning on the rock reinforce this duality.
Light as Deterrent: Lexie’s notes that “they don’t like the light” and her removal of light bulbs suggest a belief that darkness is necessary for something to emerge—or that light protects against it.
Measuring the Unknown: The grid and weighted measuring tape symbolize Lexie’s attempt to quantify and understand something that may be beyond human comprehension—the depth of the pool, and perhaps the mystery of what lies beneath.
Paper Boats and Communication: The paper boat with a message is a motif of attempted connection, echoing the childhood game of sending notes down the canal. Lexie’s final message to Jax is a plea that went unanswered.
The Price of Miracles: The historical warning “beware” and the town’s stories about the spring’s curse suggest that any miracle obtained from the water comes at a cost.
Transformation and Hidden Identity: The recurring phrase “isn’t who she says she is” connects Lexie’s notes to Declan’s nightmare fish, implying that things—or people—may change into something else.

Why This Chapter Matters

This chapter deepens the central mystery of the pool and Lexie’s death. It reveals the extent of Lexie’s obsession through her coded notes, her research into the property’s history, and her physical attempts to measure the pool’s depth. The discovery of the “beware” rock connects the present to a centuries-old warning, suggesting that the spring’s power is not a recent phenomenon. The parallel between Declan’s fish incident and Lexie’s notes about hidden identities hints at a broader theme of transformation that may be central to the novel. Finally, the chapter ends with a chilling image—a shadow in the water—that leaves the reader questioning whether Lexie’s claims were delusions or something far more real.

Study Questions and Answers

Why does Jax feel guilty about both Lexie and Declan?

Jax feels guilty because she didn’t answer Lexie’s phone calls, as evidenced by the paper boat message. She also feels responsible for missing Declan’s call, which might have prevented his violent outburst at school. In both cases, she was unavailable when someone needed her.

What does the grid and measuring tape suggest about Lexie’s state of mind?

The grid of letters and numbers, along with the weighted measuring tape, shows that Lexie was systematically trying to measure the pool’s depth. This suggests a methodical, obsessive approach to understanding the water, possibly to prove that it was bottomless or to find something hidden beneath the surface. It also indicates that her behavior was not purely chaotic but driven by a specific, if irrational, goal.

How does the historical warning “prendre garde” relate to the themes of the chapter?

The warning, meaning “beware,” is carved on a rock found at the spring by the first settlers. It reinforces the idea that the water is dangerous and that seeking its power comes with a price. This connects to Gram’s stories about the spring being cursed and to Lexie’s own fate, suggesting that her obsession with the pool may have led to her death.
