Dante's Eternity (Unabridged‪)‬

A genetic legacy of pre-teen incest and rape results in a third generation set of twins with a bond beyond all normality. From childhood on, every act of violence, adultery, blackmail and murder by Dante DeMille, causes the accelerated aging and agony of his twin sister, Demi. Although they have lived a continent apart as adults, they meet after thirty years of separation. Payback is hell.
