The faithful are rewarded. Sinners return to the earth to plague the living. There is no place for science here.
Dr Rashmi Pandit retrained as a doctor before the walls came down. She's third tier. With no children, no baptism, no promise to God, she knows her body will be burned upon her death. When the gates of hell closed, the bodies of the sinners roamed the earth.
Or so the preachers tell it. Rashmi knows there must be another explanation, one that follows Koch's Postulate and Occam's Razor. But as the underground network of scientists slowly dwindles, she risks being revealed for the sinner she really is. With one of the devout sharing her bed, and her only remaining family deep within the black market, she has more to lose than just her soul.
