A young man receives a strange amulet from the hands of his dying grandfather. Attempts to find out the secret of the amulet lead to extraordinary adventures in the past and present. The owner of the amulet must monitor the balance of the worlds, which gives him enormous strength and power over them, but also imposes an unbearable responsibility for maintaining the fine line of balance. And there is another exactly the same amulet. One balances the other. Where is it and who has it? The path of destiny must connect both amulets, but do their owners want this? The book is based on the manuscripts of Igor Ivanovich Kazantsev, my grandfather, who, unfortunately, has long been dead. Its text is in italics.
