The prince, the son of King Peroz, faces a disaster partly of his own making: Ctesiphon, the capital of the kingdom, has been attacked by the dreaded Huns, masters of shamanic magic. To save the townspeople, the Prince must rely on his wits and the extraordinary power of his bola, which allows him to travel back in time and avoid certain death.
