Fear drives me forward as I rush down a rocky path in Jerusalem, trying to sort things out even as dusk makes it harder to hurry.

Am I really an American girl, cast back to the time of Jesus? Or a delusional Jewish teen, plagued with visions of a place called America, thousands of years in the future?

I don’t know anymore.

But I do know that something awful is about to happen to my Jesus: they’re going to arrest him tonight, and kill him.

No one believes me; they think I’m crazy. So it’s up to me to save him, hurrying down this dark path toward Gethsemane, toward the turning point of all history, the attempt to kill Jesus . . . toward the uncertainty of whether I can actually manage to change the future.
