Worlds Apart is a novel written by Joe Haldeman and published in 1983.
Worlds Apart is a novel in which Marianne O'Hara and millions of survivors in New New York become victims of a virus that kills anyone over the age of twenty.[1]
Colin Greenland reviewed Worlds Apart for Imagine magazine, and stated that "It feels perverse to say that a series about the near extinction of the human race seems uneventful, but somehow it does. The futuristic detail is fascinating, but Haldeman relates it in a casual, rambling way that dilutes much of its drama."[1]
