Voodoo Dawn by John Russo

Seven bodies have washed ashore in Florida, and one of the drowned "boat people" is Chango, the voodoo sorcerer whose leather pouch holds a child's severed finger.
The sorcerer and his six followers have been buried in a mass grave. Prayers have been spoken to exorcise their unholy powers of the voodoo gods. But Chango's spirit still prowls the moonlit beaches, taking victim after victim, leaving them cannibalized and dismembered. The human bodies are being used in an occult ritual. And, come morning, we will face the unspeakable terror that is . . . VOODOO DAWN!
