Children Of Two Suns.

"Fifty times more brilliant than the full Moon, Lucifer had transformed the skies of Earth, virtually banishing night for months at a time. Despite its sinister connotations, the name was inevitable; and indeed 'Light-bringer' had brought evil as well as good. Only the centuries and the millenia would show in which direction the balance tilted."

- Arthur C. Clarke, 2010: Odyssey Two.

It's been thirty years since this first sequel to 2001: A Space Odyssey was written; since then, thanks to Clarke's vivid and imaginitive prose, I've always been fascinated with the prospect of seeing two Suns share the heavens.
