Little Magnus is afraid of trolls under his bed. Pop and Mane talk to him him and eventually manage to convince him that trolls actually prefer goats, not children. Later that day, when they go to the castle for one last visit, little do they know that all this troll-talk will come to life. Adventures through dense forests, fighting off trolls, and searching for healing plants to cure a small boy, "The Valley of Trolls" is a scary, and rather action-packed and riveting tale, the last from Gotthardt's "The Enchanted Castle" series. A more than satisfying conclusion and definitely recommended.
