The Treehouse in Releasing 10: A Sanctuary of Love and Loyalty

What Is the Treehouse?

The treehouse is a handmade wooden structure built inside a large oak tree in the meadow near Old Hall House, the Young family home. It first appears in chapter 51 (March 17, 1997), when five childhood friends—Lizzie Young, Hugh Biggs, Claire Biggs, Gerard “Gibsie” Gibson, and Patrick “Feely” Feely—decide to build a treehouse after the St. Patrick’s Day parade. The project quickly derails when they discover a rusty bicycle in a shed, but the treehouse floor is laid that day, and the structure is later completed. By the time of chapter 86 (August 28, 1999), the treehouse is fully finished and becomes a private retreat for Lizzie and Hugh.

Where the Treehouse Recurs

The treehouse appears in three key narrative moments, each marking a shift in Lizzie and Hugh’s relationship:

• March 17, 1997 (Chapter 51): The friends attempt to build a treehouse but get sidetracked repairing a bicycle. Only the floor is laid. Lizzie’s mother, Catherine, observes the children, and Hugh assures her that Lizzie is doing well. The treehouse exists as a potential space—a shared project that represents childhood camaraderie.

• August 28, 1999 (Chapter 86): During a camping night, Gibsie tells the legend of the Banshee of Ballylaggin. Later, Lizzie joins Hugh in the treehouse, where he confesses his love and asks her to be his girlfriend. Lizzie accepts, and they share their first official kiss as a couple. The treehouse transforms from a group project into a private sanctuary for a deepening romantic bond.

• March 17, 2000 (Chapter 91): Hugh and Lizzie sneak off to the treehouse while their friends hang out at his house. Hugh lies to his mother, claiming Lizzie is “just a friend,” but inside the treehouse, Lizzie initiates a kiss. Hugh internalizes this as a permanent commitment. The space now symbolizes both secrecy and the weight of promises made in the face of family denial.

How the Treehouse’s Meaning Changes

From Play to Love

In its first appearance, the treehouse is a chaotic, unfinished project—the children get distracted, lose a hammer, and never finish the walls. It represents the unstructured joy of childhood friendship. By the time it reappears two years later, it has become a finished, private hideaway. That enclosure mirrors the way Lizzie and Hugh’s bond has matured from playful friendship to romantic intimacy. The treehouse is no longer a shared project among five friends; it is a space for two.

From Open to Secret

During the March 2000 scene, Hugh outright denies the relationship to his mother while simultaneously using the treehouse as a hiding place. This introduces a layer of secrecy: the treehouse becomes a physical location where the truth is spoken but hidden from the adult world. The dichotomy between Hugh’s public lie (“she’s just a friend”) and the private commitment in the treehouse foreshadows the conflicts to come—the need to protect their relationship from external judgment and internal shame.

From Escape to Anchor

For Lizzie, the treehouse is an escape from the chaos of her home life. Her mother’s cancer, her own bipolar diagnosis, and the trauma of past abuse make everyday life overwhelming. The treehouse offers a literal elevation above the ground—a place where she can breathe. For Hugh, it becomes an anchor: he uses the treehouse to stabilize her during episodes, as seen in chapter 92, where he finds her after a nightmare and helps her dress. In that scene, the treehouse is not mentioned explicitly, but the pattern of Hugh being her grounding force in quiet places is consistent. The treehouse is the emblem of that private support system.

Character and Theme Connections

Lizzie Young

The treehouse is one of the few places where Lizzie feels heard and safe. In chapter 51, Catherine Young notes that Lizzie is “laughing more”—the treehouse project coincides with Lizzie’s early stability after starting medication. Later, when she initiates a kiss in the treehouse, it shows she is capable of seeking connection rather than retreating into silence or self-harm. The treehouse becomes a stage for her vulnerability and agency.

Hugh Biggs

For Hugh, the treehouse is a place of duty and devotion. He builds it with her, protects her inside it, and lies to his mother to get there. His commitment is sealed in the treehouse: when Lizzie kisses him on March 17, 2000, he “internalizes the kiss as a permanent commitment,” as the chapter outline states. The treehouse is where he assumes responsibility for her well-being, a role that becomes increasingly heavy.

Childhood Sexual Abuse and Grooming

The treehouse is a counterpoint to the spaces where abuse occurred. Thematic pages explore how trauma invades private spaces; the treehouse is deliberately kept pure. When Lizzie is found naked after a nightmare in chapter 92, Hugh helps her dress in her living room—not the treehouse—implying that the treehouse remains untouched by that horror. It is a place where she can exist without the past bleeding in.

Secrecy and Gaslighting

Hugh’s lie in chapter 91 (“she’s just a friend”) is a small act of gaslighting directed at his mother, but it also foreshadows how the adults in the novel will deny Lizzie’s trauma. The treehouse becomes a conspiratorial space where truth is spoken but hidden from people who would not believe it.

Grief and Loss

The treehouse is also tied to loss. Catherine Young’s absence during the treehouse building (she watches from the door) prefigures her eventual death. The meadow and the treehouse are near Old Hall House, which later becomes empty. The treehouse outlives the original family, much like Lizzie’s childhood innocence.

Study Questions and Answers

1. Why does the treehouse remain unfinished during the 1997 scene, and what does that suggest about the children’s friendship? Answer: The treehouse remains unfinished because the children get distracted by a bicycle and lose the only hammer. This suggests that their bond is built less on completing projects and more on shared spontaneity and mutual support. Hugh reassures Lizzie’s mother that Lizzie is doing well, indicating that the process of building together matters more than the final structure.

2. How does the treehouse scene in chapter 86 differ from the one in chapter 91 in terms of secrecy? Answer: In chapter 86, Hugh confesses his love openly; the treehouse is a romantic sanctuary with no deception. In chapter 91, Hugh lies to his mother about Lizzie being “just a friend” before sneaking into the treehouse. The later scene introduces a layer of secrecy, suggesting that the relationship must be hidden from adults, foreshadowing conflicts around family acceptance and Hugh’s internal conflict between honesty and protection.

3. What does the treehouse represent for Lizzie’s mental health journey? Answer: The treehouse represents a safe, elevated escape from her chaotic home life and the intrusive memories of abuse. It is a place where she can express affection without fear, as when she initiates the kiss in chapter 91. Unlike her bedroom or living room, which are invaded by trauma and family illness, the treehouse remains a space of agency where she is in control.

4. How does the treehouse connect to the theme of loyalty and sacrifice in the novel? Answer: The treehouse becomes a physical symbol of the oath the friends made in chapter 28: “We keep each other’s secrets and stick together, no matter what.” Hugh sacrifices his honesty to preserve the treehouse as a private space (lying to his mother), and Lizzie sacrifices her silence by initiating intimacy there. Their loyalty to each other is tested and affirmed in that wooden structure, making it a monument to their bond.
