One of the breakout stars of the original Halo was 343 Guilty Spark. And like all good celebrities, Sparky parlayed his notoriety into a media empire that included a reality show [Keeping Up With The Reclaimers], a perfume [Eue De Digits], and even a line of decorative dish towels. And now he’s back, reuniting with his old pal Rion — and writer Kelly Gay — for the new novel, Halo: Point Of Light (paperback, Kindle, audiobook), the sequel to Gay’s Halo: Smoke And Shadow and Halo: Renegades. In the following email interview, Gay talks about how the Sparkster inspired her to write this sci-fi space opera story.
