Just finished up Seven Eves by Neal Stephenson (sci-fi/fiction in the near future), upon recommendation by a co-worker. I don't want to give away any of the plot, so I'll address some generalities. Overall, enjoyable, and recommended for a light read. Definitely more of a "holistic" or overarching humanity-type story than I originally was expecting.
There is an event early in the book that changes the course of humanity. I thought the book would revolve around finding out how/why it happened. Nope. It's left ambiguous. So, I was reading the book expecting one kind of story and got something else entirely. I think it was just a tool to advance the story, but IMHO I think they could have just come up with an answer instead of leaving that point hanging. The beginning of the book does a good job hooking you into the characters and plot.
The second third of the book was a somewhat gritty look at the "immediate" aftermath and at about 2/3 through does the title of the book make sense.
The last third of the book goes off into a bit of a different path than the previous 2/3 but ends up tying most of it together at the end.
I thought it was an interesting story to tell overall with an aggressive but somewhat plausible approach, but the last third was just a bit weaker in my opinion - some of the technical aspects in particular seemed somewhat lacking but it sure was a heck of an idea that was implemented. Also, the storytelling seemed to shift a bit in tone that didn't jive with the first 2/3. I saw some of the bits at the end coming before they went into detail. One of the characters was played a bit over the top - but I think it was somewhat necessary to advance the story being told. Some of the background/descriptions seem pretty long-winded (technology, physics, genetics, etc.) and in a couple of cases it seems that the physics wouldn't always match the descriptions in the book. Pretty much minor quibbles in an otherwise enjoyable fiction read, though.
