The Rain — A. Ka

Isaac's life isn't that bad. It's not that good, either. He makes a fair amount of money, working in Venice as a doctor, but he doesn't receive much respect. And he lives by himself, away from his son and father in Delphi. He's resigned himself to the lonely life of a Jewish widower until he meets a strange Swiss "lad" who doesn't care to look or act like the woman she really is. She says crazy things, too, about a potion that repeats time and "The Delirium," a plague about to destroy the world. Isaac is skeptical of her claims, yet enamored by her cheeky attitude. His family might not find her so amusing, though, as Isaac and the Swiss lad travel from Venice to Delphi, in search of a legendary spring to brew her potion. Still, she is quite persuasive, and quite beautiful, and Isaac can't resist her requests... no matter how impossible they may be.
