Set from December 1999 to Mardi Gras 2000, Messiah introduces two remarkable young women: Felicity, a girl detective in New Orleans, and Andrea, a Sarajevan orphan who has found asylum in Jerusalem after internment in a Serbian POW camp. Felicity and Andrea, both presciently self-aware, come to believe they are the two severed halves of a whole entity, eventually finding each other amid the chaos of millennial fervor. Their special mission: to fulfill an extraordinary destiny as Armageddon sweeps the earth.
