Perfect for you if...

You enjoy mysteries with genuine atmosphere and a sense of creeping dread that builds steadily rather than relying on jump scares.
You're drawn to stories where young protagonists uncover secrets that adults have either missed or deliberately hidden from them.
You like Scandinavian settings that feel like characters themselves, with isolation and landscape playing crucial roles in the tension.

Maybe not for you if...

You prefer fast-paced plots that reveal their central mystery within the first few chapters.
You want romance or humor woven through the narrative as a counterbalance to darker elements.
You're looking for high-stakes action sequences rather than psychological mystery and atmospheric dread.

About this book

Twelve-year-old Tuva lives on Harö, an island in the Stockholm archipelago, where she mostly keeps to herself at school. When a classmate goes missing, Tuva finds herself drawn into a mystery alongside Rasmus, a new student. Together they witness something unexplainable in the woods near the water—something that may be magical or evil. Tuva holds a key to understanding what happened. The disappearance is not isolated; other people around the islands have vanished from their boats throughout the fall, leaving no trace. As Tuva and Rasmus search for answers, they must uncover the secrets hidden beneath the surface of the water before more people disappear.
