FYI: These sci fi books are "Rated M" for Mature Audiences; since there is action, drama, romance and comedy... and sex. One of my fans called it "Game of Thrones in space".
Now I don't randomly kill off my characters like they do in that HBO show, but people are born and others die, in my sci if saga. But I believe in building a legacy for my original characters, without hitting the fans with some BS storyline. For instance, I won't kill my Wolverine or Nightcrawler, only to bring them back in 6 months when comic book sales are dwindling ;)
