Boris sat down on a log, gasped heavily and wiped the sweat from his forehead with a dirty hand. The middle of June was exceptionally hot, and the forest around Wolf Mountain, though dense and green, held the heat like a trap. Despite this, the boy was not complaining. It was here, away from the town and school troubles, that he felt most comfortable. Next to him stood Lena.

A shadow was emerging from the tall grass, too big for a fox, too quiet for a boar. Boris furrowed his brow. The tales of Wolf Mountain that his grandfather had told him were suddenly much closer than usual. - 'Let's walk closer, but be careful,' he replied, reaching for a branch as if it could protect him.

On her shoulder was a raven, and beneath her feet stretched unusual, wriggling roots - as if a tree were growing inverted, straight up from under the ground. Boris felt he should run away, but could not look away. Suddenly the figure turned its head and looked straight at them. Its eyes - once green, once grey - shone with a strange light.
