Isaac Asimov's "Foundation" series famously examines the collapse of a decadent stellar empire through the framing device of the eponymous Foundation, which is trying to shorten the dark age between united civilizations. This series examines a similar imperial collapse, but through the device of an attempt by the last remaining Imperial Marines to build a new civilization from the ashes of the previous empire.
The series alternates between books showing the rise of the new state and its attempts to avoid being destroyed by neighboring predators with largely standalone books showing the collapse as seen on a single planet in the empire. This is one of the standalones.
Here, the protagonist is a journalist who is fired for examining details that a large corporation would prefer not to be seen, and who then joins a new journalistic startup, nominally supported by a university.
The foreground characters are drawn well enough to carry the story. In particular, the protagonist journalist has a family that is badly shaken by his firing and an interesting backstory of rising from one of the slum estates. The plot is a bit rote, with a secretive corporation trying to hide, ... something, which becomes the focus of the journalist's investigation.
The ending is a bit convenient for my tastes, but this is ameliorated a bit by the epilogue, which discusses the short-term aftermath of the collapse and recognizes the coming problems.
Nuttall is an amazingly hard-working author, with something like 200 published books. Possibly as a result of this prolific writing, some of his books don't stand up well to close examination. This is not one of the better books in this series.
