The story begins with a prelude section four years before the main story, with Detective Bartholomew Nyquist investigating a murder with his unwanted, newly minted partner Usula Palmette. Things go wrong, but not because of the case--they're caught off guard by a series of major bombings that shake the Moon dome to the core. (Oh, did I mention the story takes place on the moon, at a point where it's been colonized with a series of domes? Well, pretend I said that.) Then we get the jump. Four years later, the day is remembered as Anniversary Day, and this Anniversary Day, whoever was behind the original bombings wants to make it clear they were just an opening act. Identical men are performing assassinations of the Moon's top political figures, and things only get worse from there. The story's told from the viewpoints of a number of different people trying to hold things together and get to the bottom of the attacks: Nyquist, now a high-ranking detective; Flint and his prodigy clone daughter Talia; Noelle DeRicci, Chief of Security for the United Domes of the Moon, and others. Starting the book with a low level case was a good idea; while it takes time to see what relevance the case has to the larger story, Rusch provides the reader with an entry point before the main plot, which is largely an escalation of terrorist disaster from the perspective of the government and law officials left without their heads of states. What follows is a little confusing and scattered at first, but once the story picks up steam, the plot really carries everything forward--Rusch is *good* at thriller-type writing. Unfortunately, the ending is somewhat of a low point, as there's not so much a resolution as trailing off. As a thriller book, the characters aren't terribly well developed; the focus is on dealing with the rising crisis, not with character arcs. The villain side of things is kept deliberately dark, but even then, it's a pretty clear white hat against black situation, as the terrorists we do see are bitter, fanatical, or a bit of both. Still, none of the characters are off-putting, and they fit the story well enough. I didn't know until after I'd finished the book that it was the eighth in a series, or at least, the eighth book featuring Flint in particular. That explains some of its stranger elements--for example, we don't find out that aliens exist and are a regular feature in this future until a quarter of the way through the book, and that seems like an odd choice unless it was an event described in an earlier book that didn't need to be elaborated here. I'd also imagine that I'd feel a little more positive towards the characters and book as a whole if I was familiar with the history they might share in earlier stories. It's to Rusch's credit that I didn't feel lost, or even missing out on events. It's a good sci-fi thriller, but the hump in the first third and the lack of resolution are definite detracting points for me. On the other hand, I got it from a StoryBundle, and so for the price and what I was expecting, it was definitely worth reading. I don't know if I'd go out of my way to find the rest of the series, but if our paths cross, I'd be interested in reading more.
