mariefred (sweden)

"Strange things are happening in Mariefred. The town hides a secret library that the forces of good and evil fight to find. It is protected by two elderly siblings Estrid and Magnar. Viggo and Alrik are chosen to be their successors, but the old guardians do not believe they are prepared. When someone plants a cursed nithing pole in the garden where the boys live, all four must work together to break the curse before it's too late"--Amazon.

"A strange beast attacks the townspeople of Mariefred at night. Brothers Viggo and Alrik must stop it before it hurts others. Could it be a werewolf? How do you fight something like that? They turn to the secret library for information. They also ask Damir for advice, but can they trust him?"--Provided by publisher.
