I obtained this book through the Kindle Unlimited program.
Open war exists between the Humans and the Galactic Union. More precisely, that conflict is instigated and carried out by certain elements of the Mercenary Guild, lead by General Peepo; and targeting Human mercenaries, with special emphasis on the Four Horsemen.
In this installment, the agents primarily used by General Peepo are the MinSha. Operational command is held by Major General Drehnayl, while Lieutenant General Chinayl is the behind-the-scenes decision maker.
(NOTE: In the American military, these ranks would signify that Chinayl, with three stars, outranks Drehnayl, with two stars. A lieutenant general outranks a major general, as a function of relationships to two obsolete rankings; the Lieutenant General was second in command to the Captain General, while the Major General is derived from the Sergeant Major General. However, it is not possible that the actual rank structure of the MinSha and the American military are a one-to-one rank equivalent. Their actual ranks are likely something like GerbSn893^%jk and VrZum*)@gf, and taste purple and footwear, respectively. )
The mission: wipe out Human colonies. Kill them all.
MinSha carry out their orders cheerfully and to the very best of their abilities, but General Drehnayl also has a personal animus toward the Humans: she was related to some of the MinSha killed by rogue Humans during First Contact. And, as the rogue attacks came from representatives of a polity from which Asbaran Solutions eventually derived, her hatred toward that group is particularly intense. Golly; I wonder if this will cloud her judgment?
A Very Strange Thing has happened to the first target of Gen. Drehnayl, the planet of New Persia: all of the settlements, save one, have been destroyed by nuclear weapons. The only location where Humans remain is devoid of fighters, with only women and children present. Certain of Drehnayl's staff believe this should result in a change of targets. Nah, says Drehnayl. We're here already. Let's kill the civilians.
Actually, she's not QUITE that calm toward those so bold as to make the suggestion. And thus, a bit of discord finds root.
But, the facts behind the Very Strange Thing are ignored. Wonder what's up with that?
The First Human Peacemaker, Lieutenant Jessica Francis, back home after her work on Weqq, is given the task of determining why there has been no communication with New Persia; intelligence, in this instance, has provided the correct lead that Gen. Drehnayl is responsible. She is given a memorable send-off by her supervisor; one might even say it's the farewell of a lifetime. She will not rest until she brings resolution to the assignment she has been given, because that is the way she s wired, and because that is the choice she has made for her life.
While she is doing that, the Peacemaker Council has to face the fact that with the active hostility of the Peepo-lead Mercenary Guild, their role as Galactic Cops is in imminent danger of ending catastrophically. That's the deal with cops; there are ALWAYS a lot more of Them than there is of Us.
Meanwhile, the THIRD Human Peacemaker, Jackson Rains, is being an ass. It's a role he has developed to a high degree, and he rather stays in that role for the entirety of the book. I don't know why he gets such devotion from his comrades. He seems to use every opportunity to whine, and when no opportunity is available, he makes one. Maybe he'll eat something poisonous soon.
With respect to other major plot threads and characters: I leave those as an exercise for the reader. You will NOT be disappointed!
