How much do graphic novels and science fiction overlap? Apparently, enough for publishing giant Hachette Group to fold its graphic novel imprint, Yen, into its science fiction imprint, Orbit. The resulting fusion will be known as Orbit, and will be run by Orbit founder Tim Holman. Neither label will shrink, and in fact Orbit is still on track to expand to four titles per month in 2009, five in 2010, and six in 2011. [Publishers Weekly]
