Immortal by Angela Elwell Hunt

Claudia is stunned by Asher Genzano's story. Who is he? A fanatic? A religious zealot? A raving lunatic? Or is he what he says he is-a 2000-year-old man cursed with immortality and on a holy mission to prevent a global cataclysm?

Her search for answers leads Claudia into the past where myth, history, and prophecy intertwine in ancient legends of the Wandering Jew, biblical warnings about the Antichrist, and eyewitness accounts of the Crucifixion, the Inquisition, the Holocaust. What Claudia learns challenges everything she believes . . . about life, love, and God.
