Horrorstör is an intriguing story that follows Amy and her boss Basil as they get entangled in a series of mysterious events at Orsk store. Every night, strange occurrences take place, leaving the store in disarray. To solve the problem, they decide to patrol the store overnight. Amy agrees to do so because she needs the money to pay her rent. However, things take a bizarre turn as soon as they start their shift.

The author's ironic and sarcastic tone towards a Swedish interior shop is hilarious and well-crafted. Each chapter is named after a Scandinavian-inspired piece of furniture, and the catalog pictures at the beginning of each chapter are aspirational but also give away some of the events that take place in the store. Although the story has its scary moments, it falls a bit flat. Nonetheless, the concept of the book is impressive, and it is worthy of a four-star rating.
