However, the journey isn't an easy one and once again tragedy follows them. On the island of Jamaica, the couple encounters a powerful priestess who is determined to raise the dead--after she adds Calpurnia to her undead army.
Muncie embraces his former identity as he takes up the fight for Haiti and saves his friend from the Queen Pi, the voodoo queen who could end them all. The paranormal story of Calpurnia Cottonwood continues. It's southern gothic horror with a twist of Caribbean magic! Beyond Seven Sisters is the finale episode of the original Seven Sisters series by M.
