What This Theme Explores
The Supernatural and Possession probes what happens when evil refuses to end with death, asking whether malice can outlast the body and commandeer the living. It interrogates agency—what it means to keep hold of the self when an external force presses in—and reimagines a lake not as a setting, but as a conduit between worlds. The theme also complicates accountability: if a soul can cross into another body, who can be saved, and who must be fought? Beneath the hauntings lies a psychological corollary—how trauma and guilt “possess” people long after the initial harm.
How It Develops
The novel plants the supernatural early as whispered rumor. Casey Fletcher hears childhood ghost stories about Lake Greene and, around a campfire, Eli Williams retells local lore about reflective surfaces trapping souls. Casey treats it as atmospheric color, not a rulebook—an attitude that primes both her and the reader for misdirection.
Through the middle stretch, the story resolutely masquerades as a domestic thriller. Casey’s fixation on the glamorous couple across the water persuades her that Tom Royce is dangerous and that Katherine Royce needs rescuing. Human evils—abuse, secrets, manipulation—fill the frame, shoving the supernatural to the margins and creating a comforting genre expectation the novel will later shatter.
The final act detonates the old framework. Tom confesses a belief in possession; Katherine speaks in the voice and with the knowledge of Len (Leonard Bradley), confirming the lake’s folklore as literal truth. The climax redefines “saving” someone as a metaphysical maneuver: Casey exploits the lore’s rules to draw Len’s soul into herself and sink him, yet the ending leaves the water unsettled, hinting that what the lake takes it never fully releases.
Key Examples
The narrative carefully lays down rules for possession long before it enforces them, then revisits those rules at the moment of crisis.

Foreshadowing through folklore
At night, you can’t see your reflection on the water. Centuries ago, before people knew any better, it was a common belief that reflective surfaces could trap the souls of the dead... and that if you saw your own reflection in this very lake after someone had recently died in it... it meant you were allowing yourself to be possessed.
Eli’s campfire tale is more than a mood-setter; it codifies how souls pass across the lake’s surface. By embedding the rule in a “spooky story,” the novel disguises a literal mechanism as superstition, ensuring the later twist feels both shocking and fair. -
The first explicit explanation
“I think—I think it’s true. I think something was in that lake. A ghost. A soul. Whatever. And it was waiting there. In the water. And whatever it was entered Katherine when she almost drowned and now—now it’s taken over.”
Tom’s confession reframes him from suspect to reluctant witness, shifting the inquiry from whodunit to what-is-happening. His language—hesitant yet precise—bridges rational skepticism and supernatural acceptance, guiding the reader to do the same. -
The voice of the possessed
“You sure you want that, Cee?”
...
“I haven’t forgotten that you killed me.”
Katherine’s body delivering Len’s private nickname and grievance collapses doubt in an instant. The possession manifests as intimate knowledge and vindictive intent, turning the supernatural into a personalized continuation of Len’s abuse. -
The engineered transfer
“Keep going,” I whisper against his lips. “Don’t stop. Leave her and take me instead.”
Casey weaponizes the lake’s rules, recasting sacrifice as a strategic act of containment. The scene underscores the theme’s moral complexity: salvation requires submission to the very force one fears, and heroism becomes a controlled surrender of self. -
The lingering threat
“Do you really think they’re gone?” Katherine says. “What if they’re not? What if both of them are still out there, waiting?”
The closing unease resists tidy closure, insisting that evil persists in liminal spaces. The lake remains an active threshold, preserving the story’s aftertaste of dread.
Character Connections
Casey Fletcher begins as a skeptic whose lens is trained on human malfeasance, not metaphysical threats. Her arc pivots when she accepts that the only way to save another body is to risk her own, transforming guilt into agency: she chooses to be a vessel to end a cycle of harm she helped initiate.
Len (Leonard Bradley) embodies evil that metastasizes beyond death. In life, he exerted control; in death, he perfects it, parasitizing another body to continue the dominion he wielded. The possession turns his violence into something literally invasive, making the theme’s horror inseparable from his character.
Katherine Royce is the battleground where identity is contested. Her erratic behavior, first read as signs of marital abuse, becomes evidence of a soul-struggle: moments of lucidity flicker against Len’s encroachment, dramatizing the fight to remain oneself under internal siege.
Tom Royce is the novel’s counterintuitive truth-teller. His frantic belief isolates him, yet his refusal to dismiss the supernatural positions him as both unreliable and correct. He models the moral imperative to act even when the explanation makes you sound unhinged.
Eli Williams functions as the folkloric archivist whose tale proves instructional. By honoring inherited knowledge, he becomes the story’s quiet authority, reminding us that the past’s warnings often encode survival strategies.
Symbolic Elements
Lake Greene
Described in the Prologue as “darker than a coffin with the lid shut,” the lake is a repository for the dead and a medium for their return. It is leisure on the surface and burial beneath, the tension that defines the book’s genre turn.
Reflections
Mirrors, windows, and the water’s skin signify the membrane between life and afterlife—thin, beautiful, and treacherous. Katherine’s fixation on her reflection dramatizes a self being edged out by an intruder, image standing in for identity.
The Storm
Tropical Storm Trish strips away modern safeguards—power, communication, help—so the world can revert to old laws. In that isolation, folklore becomes physics, and the supernatural is not only plausible but inevitable.
Contemporary Relevance
Possession speaks to current anxieties about autonomy and the fragility of identity in a world of algorithms, manipulation, and curated selves. The novel’s hauntings double as metaphors for trauma and addiction, showing how past harms and private vices can commandeer a person’s choices. Casey’s alcoholism and guilt behave like a pre-supernatural possession—habits and memories that occupy the will—while Katherine’s struggle literalizes the fight to reclaim one’s body and voice from someone else’s control. The lake, like the internet’s reflective surfaces, turns watching into a risk and recognition into a gateway.
Essential Quote
“Keep going,” I whisper against his lips. “Don’t stop. Leave her and take me instead.”
This line distills the theme’s paradox: the path to liberation runs through voluntary surrender. By inviting the possessing force into herself, Casey turns victimhood into strategy, demonstrating how knowledge of the supernatural’s rules can convert terror into agency—at terrible personal cost.
