Interstitial (Interstitial, #1)

Love triangles. Alien monsters. Planetary war. Just another day in space. Sebastien ven Hester, decorated war hero and captain of the sentient cargo ship Naurus, can face any danger--except his own feelings. Jason North, his pilot, finds out the hard way that Seb's not ready for a relationship after his recent divorce. And Jatila Kan, their engineer, discovers her feelings for North aren't returned--because her lover's pining after another man. Not the best situation for a crew starting a three-week run across the galaxy. But there are bigger terrors in space than their messy love triangle. A ruthless, horrifying enemy stands ready to test them to their physical and emotional limits. Failure means certain death not only to themselves and their passengers, but to the entire planetary alliance
