#Obsessed: Our growing interest in psychological fiction

The summer of 2026 came with a new, subtle form of horror that has taken the world by storm. Given the recent success of the movies Obsession and Backrooms, both of which hit theatres this summer, we wanted see if this interest had carried over to Canadian readers. So, we looked at how books with a Psychological BISAC code have been doing over the second quarter of this year in comparison to the last year.
