I like relationships (love interests) in the books I read. It adds to the story and creates interesting plot points and conflict both internal and external to the characters. As I read this series I always thought that Cam and Nathan would end up together as they started so far apart. I'm not so sure anymore and I'll admit I'm a little disappointed about it. I always thought of Nash as just being a fling type thing for Nathan and it didn't generate a lot of interest for me. I hope Nathan doesn't end up with some random character thrown in at the last second. Either way I really enjoy the series and look forward to the next book.
I also like Cam and Nathan... but there will have to be someone inserted above them for a while for that to come about... Perhaps after their relationship is established (Cam and Nathan), that injected superior will die, leaving leadership of the fleet to Nathan....
Vlad could fit with Abby -- Vlad and Nash would also be interesting.
