- Smaller scale. Like Traitor General, Blood Pact uses a much smaller roster of characters than the typical Ghosts novel, simply by dint of the fact that the base is on lockdown for the duration of the story, and only the Ghosts outside the cordon contribute to the show.
- Cloak and Dagger. This is a 'spy hunter' flavor of story. It sort of reminds me of a Craig Thomas novel I once read about an infiltrator into Soviet Russia being hunted by the KGB.
- The Names Of Death. There's a Blood Pact soldier that has taken as his 'rite' the task of speaking aloud all of the names of death. There are a few interesting interludes with him through the story, and one hilarious moment that makes bearing with it all worthwhile.
- The Blood Witch. Yeah, I'm not crazy about all of the magic and occultism in this series sometimes. There's a lot of that in this one. If it's been bugging you, heads up.
- Section. There are a lot of new Commisars to keep track of, and a few old friends too. Some of them seem like they might be important later, and I'm not crazy about the task of keeping straight a whole bunch of new characters who are essentially the same guy. With characters like Hark or Ludd, who have different mannerisms, it's not a problem, but the majority of Imperial Commisars are largely identical.
- Current. Yeah, this is the last novel in the line at the moment, and is not available in an omnibus. So if you have been reading this series on the cheap, like me, you are sad to see the last page. Now I have to wait until more are written. Drat.
