Grade eight attendance sheets are an existential void from which no mortal soul returns unscarred, yet here we are dissecting Possession Island: A Novel by Sarah McCarry because a decent joke or a sharp narrative hook is the only thing standing between my sanity and a complete collapse into the linoleum floor.

The premise gives us Angela Bell returning to her mother’s gothic Pacific Northwest tourist trap of a hometown only for her estranged best friend to end up brutally murdered, leaving Angela cornered by a botched police investigation. Naturally. Because no literary protagonist can simply walk down to the local bodega for a bag of chips without stumbling over a corpse or uncovering a century-old town curse involving vampires and petty high school grudges.

Speaking of absolute nonsense, why do we constantly subject ourselves to reading about moody teenagers solving crimes when I spent twenty uninterrupted minutes this morning trying to explain to twelve human children that the plural of octopus is not octopussies? A kid literally cried because I wouldn’t let him name the classroom hamster “Apocalypse.” It makes me want to scream into a bucket of industrial-strength sanitizer. At least Sarah McCarry has the decency to pit Angela against her former nemesis, Sally Raleigh—trapped by family duty and a charismatic twin—in an alliance born of grief and small-town claustrophobia.

Shadows, Doppelgängers, and Damp Flannel

The thematic mechanics rely heavily on the tired trope of the literary offspring haunted by maternal shadow-work. We have seen this exact mood board executed with varying degrees of success in Plain Bad Heroines and the endlessly undulating adaptations of Anne Rice. Yet, the queer gothic framing suggests a welcome dose of teeth—literally, if the marketing copy is to be trusted.

Wait. Let me backtrack entirely. The marketing copy actually promises nothing of the sort regarding literal biting; it is probably just a metaphorical reclamation of female rage, which means we are in for three hundred pages of atmospheric brooding, damp moss, and lingering subtext that never quite transforms into the bloody spectacle we are promised.

The synopsis leans entirely on atmospheric shorthand. Remote island? Check. Dead best friend? Check. High school enemies forced to cooperate while harboring dark secrets? Double check. It is a paint-by-numbers template for contemporary dark academia, relying on vibes rather than mechanical originality. And yet, McCarry writes with a precision that usually elevates these predictable structural beats into something genuinely sharp.

The tension hinges on the lies these characters tell each other, which brings to mind the absolute nightmare of trying to police hallway gossip between periods when the hormonal fluctuations are severe enough to alter local gravity.

Anyway, the book drops in December of 2026, which gives us plenty of time to brace for the inevitable wave of breathless blurbs comparing it to Interview with the Vampire. Let us just hope the prose carries enough bite to survive the comparison.

I completely forgot to take the trash out and I can hear the diesel engine of the garbage truck rumbling down the alley right now.
