In the Sacred Gene, LaVay presents a premise much more realistic than some contemporary stories. It is commonly acknowledged that brothers and sisters are more genetically identical to each other than children are to their parents. Based on this reasoning, Jesus the Christ would be genetically closer to his brothers and sisters than to his mother and father.
Presented as a non-stop action-thriller blended with genetic fact, LaVays novel asks what happened to the genetic line of Christ's brothers and sisters. Has their line survived? Has the same Devine DNA recently been reactivated just when humanity needs it most? And who are the "people" left here on earth to comfort us?
In a world where science and theology rarely agree, LaVay shows the double helix may not be the only mystery to intertwine mankind.
