A series-ous matter

Today is release day for the umpteenth James Bond movie. I suspect there's hardly an adult or teen living in a First World country who doesn't recognize the name. Franchises continue for a reason -- audience loyalty -- and not only on the big screen. Novel series have likewise been all the rage in recent years.

Marcus Judson Book #1

Many of my books are entirely independent of one another, but I've also been involved in two literary series. The Fleet of Worlds series (with Larry Niven), ultimately of five novels, takes its name from a unique astronomical feature -- the eponymous grouping of flying worlds! -- that figure throughout. The InterstellarNet series, of three novels, is named for the technological glue -- an interstellar comm network -- whose creation, evolution, and consequences underpin, well, everything that happens across a growing number of species, light-years, and decades. I like to believe both series labels pique book-shopper curiosity and sustain reader interest.

Since this past May's release of Déjà Doomed, I've had something of a naming conundrum. Just as James Bond's adventures (setting aside remakes and reboots) are independent apart from some recurring characters, several main characters in Déjà Doomed first appeared in 2012's Energized. Sticking loosely with today's James Bond theme, the lead character in both of these novels, Marcus Judson, has now twice  been -- however reluctantly -- a CIA asset. And, I have to admit, thoughts of inflicting a third adventure on Marcus have been tickling the back of my mind ... 

Marcus Judson Book #2

So: what should I call this latest series? The obvious choice is Marcus Judson, and subtitle books as "A Marcus Judson novel." (Hey, going with the hero's name worked for Ian Fleming. It works, in the SF context, for Jack McDevitt's long-running Alex Benedict series.) I may very well end up going with this choice. 

But I like that my earlier series had IMO catchy names. Hence, a question to those of you who've read Energized and/or Déjà Doomed. Any thoughts about a Marcus Judson series? Any thoughts about an alternative series name?
