Supernova: A massive explosion in which a star suddenly increases its luminosity by a million to a hundred million times within hours, leaving behind a neutron star of black hole. The phenomenon is the largest nuclear fusion reaction in the known universe.

When Nightingale 229, a medical evacuation vessel, answers an emergency distress signal to a deep-space mining station, the crew discovers only one survivor--and a dying star poised on the brink of obliteration. Now they have only hours to repair their own damaged starship before the supernova erupts, but can they trust the man they have rescued, who guards a secret that could threaten all of human civilization?
