Another entry in the unfolding episodic novel, The Human Division, now out in its complete form. In this, the ninth episode, the Colonial Union, in an ongoing attempt to mend relations with Earth, has invited a contingent of Earth diplomats to observe Ambassador Abumwe's negotiations with the Burfinor, trading ships for medical technology.
Unfortunately, negotiations are barely begun when one of the Earth diplomats turns up dead--and an autopsy shows that it's not due to natural causes.
Wilson and a very interesting member of the Earth team have to find the killer to prevent the CU-Earth part of the mission from blowing up, while Abumwe has to block the Burfinors' attempts to take advantage of their suddenly precarious situation.
Still a lot of fun, with the Scalzi sense of humor on full display, while we inch closer to hints of what's really going on in the overarching conflict that unites the episodes.
I bought this story.
