Given how heavily serialized the season was, a novel set during would be rather tricky. What I could see happening is a prequel novel set aboard the Titan A set some point prior to the season.
Or, as the original poster said, during the one-year gap in the denouement of the finale.
Though personally I'd rather see more followup on the season 1 elements that seasons 2-3 couldn't sweep under the rug fast enough.
