Almost two years have passed since Jack, a student of a druid nicknamed Dragon Tongue, made a voyage with Olaf Odinbrovoy to the land of giants. Jack is now thirteen, and, according to the customs of the inhabitants of Scandinavia, he is considered an adult man. But if you are thirteen and you are already a grown man, then it’s time to go on a new journey. This time, the path lies in Elfland, the Land of the Silver Apples, the only place in the world where time has frozen still. It is very difficult to get there, the road stretches underground, and the insidious underground inhabitants are more cunning and more dangerous than the terrestrial ones. But Jack does not lose heart, he remembers the instructions of Olaf, the great Berserker warrior: "The main thing is never to despair, even if you fall off the cliff. The path to the earth is not close; little can happen while you are flying.
