In a dying world, one boy offers a glimmer of hope.

Eight years after a plague killed most of the world’s population, leaving the survivors barren, midwife Leslie travels the countryside in search of some sign that humanity may still have a future. She never expected that sign to take the form of Jeremy, a seventeen-year-old Catholic boy who claims to have been impregnated following what he believes was a visitation from the Virgin Mary.

Leslie, an agnostic, is skeptical of his story, but cannot deny what the physical evidence and her trained eye are telling her: that Jeremy is indeed carrying a child inside his body. Questions abound over whether Jeremy’s version of events is true, but even as Leslie grapples with her own conflicting feelings about faith, she knows that first and foremost she has a duty to perform: ensuring the safe birth of this child who may well be the final hope of the doomed human race.
