He who dares to cross the great rivers of Trorecheye with a weapon is a fool; before he can blink his eye, he will go to the bottom to feed crayfish. Rumor has it that the forest witch keeps a magic key in her bins, which will allow the warriors to open the passage. The Kemgorod thief Fox doesn’t really believe in magic, but for a generous fee, he goes to the enchanted forest. Only, along with a heavy carved key, the orphaned student of the healer, Marushka, falls on him. To save Three Rivers from the impending war, Fox and Marushka will have to form an unexpected alliance and go on a dangerous journey. But what if the key that miraculously survived the fire is not at all what the healer Fedora desperately tried to save?
