The Twelve Stars is the story of Herculano Fontes, a well-known astrologist, that met Destiny, who has come to propose an agreement. Herculano has to show his astrological expertise by meeting twelve women, each one ruled by one of the 12 Zodiac signs. If Herculano fails in his pursuit, he will die the death foreseen in his astrological chart. If he fulfills his quest, he may interfere with his own destiny and change it at his desire.
