Trolls is the sequel to Stallo Spjut’s previous output, Stallo, which followed Susso Myrén and her family as they confronted the reality that trolls exist, can turn into animals, and are being fed children by humans. Excited by the prospect of reading Scandi horror with folkloric creatures for the first time, I eagerly jumped in. It is clear that the novel is a sequel, as past events are immediately alluded to and discussed briefly, yet there is a sense that the reader should already be aware of previous happenings. I hadn’t read Stallo and so I found the writer’s reluctance to lay the groundwork to ensure the sequel also read as a standalone frustrating. Your first warning: it is necessary to read the first book to ensure Trolls reads more smoothly.
