I was wondering how GA chooses the titles and series' they produce for their company?  I can see they are covering a lot of the Gold Eagle book series like Mack Bolan, Deathlands, Outlanders, Destroyer.  And William Johnstone's titles get healthy nods, too.  What it doesn't seem like there are, are stand-alone novels.  Most everything done seems to be part of a series.

Would that be a popular pre-requisite?

Just curious.

Thanks. 

GraphicAudio has an editorial staff that chooses titles based on a variety of criteria.  We have done a couple of stand alone titles such as ELANTRIS, JACKKNIFE and SNAKES ON A PLANE but find that most of our customers enjoy series.  We do not accept unsolicited material.  We wish you well in your endeavors!
