• This sci-fi tale is about a futuristic time-traveling military unit who end up fighting their own ghosts. The story is told from the viewpoint of a soldier's lover who's been left behind.
• The fear of loss was behind several of the things that Newsom wrote for Divers. She told Uncut: "Everyone's getting older. When I crossed that line in my mind where I knew I was with the person that I wanted to marry, it was a very heavy thing, because you're inviting death into your life."
  
  "You know that that's hopefully after many, many, many years, but the idea of death stops being abstract, because there is someone you can't bear to lose. When it registers as true, it's like a little shade of grief that comes in when love is its most real version. Then it contains death inside of it, and then that death contains love inside of it."
