Accumulation by Aimee Pokwatka Summary: Haunted House
TL;DR: The Short Version
A buried plastic doll sits in the ivy of a 1750s farmhouse in rural New York.
Tennessee “Tenn” Cherish and her husband Ward bought the house to repair their marriage after a brutal year, and they moved in with their two young children expecting a fresh start.
What they find instead is a home where light switches hide behind doors, tools vanish, walls split open, and the past refuses to stay quiet.
Aimee Pokwatka’s Accumulation follows a family trying to tell the difference between a haunting and a breakdown.
- What it is: A domestic horror novel about a haunted house, a porous mother, and a marriage under repair.
- The setup: Tenn and Ward move their children into an ancient home. A dirty baby doll surfaces in the yard, and the house begins to come apart.
- The tension: Tenn’s history of a mental health crisis makes everyone, including Ward, question whether the danger is outside her or inside her.
- Core themes: maternal burnout, buried female ambition, unprocessed grief, and the idea that spirits need a witness rather than an exorcist.

Accumulation Book Summary
Spoilers ahead.
Tenn and Ward Trevino buy a 1750s house on Harmes Way in South Bouton, New York. Ward intends it as a gift to rebuild their marriage after a year shaped by Tenn’s mental health crisis.
Eight months earlier, Tenn had tapered off her migraine medication without medical supervision. The result was severe suicidal ideation and a fracture between her and Ward that neither has fully repaired.
While clearing the yard, Ward finds a dingy plastic baby doll in the ivy. The couple turns hiding it from each other into a private game.
Then the house starts behaving strangely. Light switches sit behind doors. Post-it notes curl and vanish. Kitchenware and tools disappear. Doors stick shut without explanation.
Tenn manages the move, the school transitions, and the repairs alone while Ward begins a demanding new job at surveillance firm IntelliVision. His work involves reviewing footage of accidents and deaths, including a cruise ship passenger who jumps overboard.
Anders develops an unquenchable thirst and nightmares about endless stairs. He chases a babysitter with scissors. Aisling fixates on house ghosts and hides cutlery.
One morning Tenn wakes with raised, welted letters on her forearm spelling “DOGHOUSE”. Soon after, Aisling goes missing and is found asleep in a collapsed doghouse in the woods with the plastic doll.
The house decays in parallel with the family. Plaster splits, floorboards release nails into bare feet, and the plumbing backs up because the leaching field was crushed and mismapped decades ago.
Ward secretly reads suicide loss support forums, afraid Tenn is regressing. Tenn begins experiencing nosebleeds, welts spelling words like “PAINT”, and memories that belong to other people, including her dead friend Crystal.
On what should be her first day at a real estate video job, Tenn gets trapped in the attic when the doorknob falls off. She loses the job before it starts.
Aisling is caught digging in neighbor Frankie’s yard at 2:47 a.m. to bury a red clay doll she built as a container for ghosts. School staff report Anders sleeping in class and drawing gravestones with Tenn’s name on them.
During a playdate, Anders’s classmate Carter sees shadowy silhouettes in the hallway, panics, and falls down the steep “Murder Stairs”. Tenn visits the historical society with records clerk Senna and learns the original owners, Elbert and Cornelia Fountain, froze to death in a blizzard.
Aisling disappears again during a rainstorm. Reviewing home camera footage, Tenn and Ward watch her pull back a wall tarp and crawl into a gap inside the living room wall.
Tenn follows her inside, takes a severe electric shock from a live wire, and pulls out a feverish Aisling. At the hospital, Aisling admits she hid in the walls hoping her parents would stop fighting.
The family escapes to a coastal Georgia resort for Thanksgiving. They visit Driftwood Beach, a landscape Ward had already seen in a dream.
Back home, time and space begin to trap them. Ward falls into repetitive loops: pouring Civil War brandy, holding bleach, or climbing a ladder in his T-shirt and socks to hang invisible spiders before falling.
Tenn flees to her Pennsylvania hometown, meets Crystal’s mother outside a hospital, and realizes the woman’s memory of a gray poodle is actually Crystal’s memory living inside her. She consults Senna and Senna’s aunt, town historian Dahlia Beckett.
Dahlia explains that Tenn is “porous” and naturally collects hungry ghosts, spirits that only want a human witness. Holding them inside makes them accumulate, feed on her, and distort reality. Tenn must become a conduit, not a receptacle.
Tenn returns home with her video camera. When Aisling starts absorbing the crowd of spirits herself, Tenn deliberately takes the entities back into her own body to protect her daughter.
Ward breaks out of his trance by declaring his love and his refusal to lose her. Using custom code he writes on his laptop, they alter Tenn’s camera to an unusual 17.17 frames per second.
The modified frame rate captures the shadow silhouettes on screen. The spirits, finally witnessed and recorded, disperse from the physical world.
In the aftermath, Tenn and Ward launch an online video art installation called Gathering Place: An Installation. Live feeds of their home stream at the modified frame rate, letting global viewers watch the last ghosts flicker and fade.
Tenn reclaims her creative identity, Ward takes on household duties and therapy, and the family settles into a shared, communicative reality. In the final scene, Tenn opens the cabinet under the sink and finds the plastic doll, placed there by Ward as a continuing joke.
