Many of us have known the horror of working retail: long hours, demanding managers, ghosts destroying merchandise after hours. Wait, what? In “Horrorstör”, Grady Hendrix imagines what might happen if ghosts ran amok in a big-box furniture store.

Amy works at Orsk, a cheaper version of a more famous furniture store. She doesn’t like Orsk. In fact, she doesn’t like much of anything. She’s behind on rent, has dropped out of college, and is facing one of the worst horrors of all: moving back in with her mother. Amy plans on getting her life together . . . someday. Until then, she spends her time avoiding Blair, an overeager manager devoted to the Orsk way of life. And then there’s Ruth Anne, who has made Orsk into not just a job but a family. Life at Orsk isn’t all it seems to be. Strange things happen at night and Blair recruits Amy and Ruth Anne to stay overnight and help him find the culprit. Corporate is coming for a visit in the morning and Blair wants everything to be perfect.

Matt and Trinity are two Orsk employees who think ghosts are behind the mysterious merchandise damages. They sneak in to set up the ghost-hunting equipment that they hope will help them start their very own TV show. The five employees band together out to find out what’s really happening at Orsk. Of course, they’re in over their heads.

The reality is linked to the history of the land itself and the evil Warden Josiah Worth. He ran the Cuyahoga Panopticon, a prison that was more dedicated to torture than rehabilitation. Prisoners spent time strapped in a chair so tightly they couldn’t move, or turning a crank thousands of times a day. Is it any wonder that Orsk is now haunted?

Amy realizes that she has to take action for the first time in her life if she wants to survive. She and her coworkers fight their way through the night, encountering angry spirits and experiencing first-hand the treatments Warden Worth bestowed upon the “penitents” in his care. When morning comes, will any of Orsk’s employees be left standing? Will any of them be sane?

Fans of “Shaun of the Dead” and “John Dies at the End” will appreciate the dark sense of humor Hendrix weaves throughout his story. Faint of stomach, beware: there are a couple of graphic scenes, but they pass pretty quickly. Each of the characters is distinct and comes across as real, not just a stereotype. Anyone who has both worked retail and likes horror stories will probably get a kick out of “Horrorstör”.
