Trilogy McCaffrey continued the biography of Killashandra Ree in two sequels, Killashandra (1986) and Crystal Line (1992). The original Continuum stories ended with Killashandra's death, while the trilogy follows her over the course of many centuries and ends on a more hopeful note as new technology and discoveries conquer many of the difficulties that made her career perilous.
