To summarize: An interesting (if predictable) plot set in a moderately unique world/galaxy, which keeps you turning pages. Unfortunately, the story is bogged down by grade-school "romance" plots and very poor character development. Also cookie-cutter plot from the last two books, but I think that was expected.
The plot is interesting enough that you want to keep reading. Not high-literature by any means, but fun, fast action which makes for light reading. Where the first and second book delivered the fun action, this book became increasingly waterlogged with hamfisted attempts at "romance". Or just downright sketchiness.
Basically, at least half the novel is dedicated the sexual exploits of the main character. Predictably, these are not well written, realistic or drive meaningful character development. This is sadly true for many novels (especially in scifi and fantasy), and to be fair, writing real romantic relations can be very challenging even for accomplished authors. This aspect of the human condition is very difficult to capture. In most novels though, these little romantic romps are usually side-plots and not very important; usually you can just ignore them.
Alas, for Tech World, these are significant plot points and relatively important to the main storyline. Which means we are subjugated to endless descriptions of McGill ogling women, thinking about them in his head, bantering with his friend, etc. It follows the exact same pattern, repeated at least four times in this book alone:
1. McGill chooses a woman to ogle -- may be an old fling or new victim
2. McGill ogles, at length
3a. Woman deflects for a few chapters
3b. Other women become mad at McGill for taking interest in someone else
4. Original woman ends up sleeping with McGill
5. Woman inevitably gets mad at McGill for
6. Cycle repeats
I understand that situations like this can and do happen in the real world. The difference is that A) every woman is enamored with the main character and B) these are all presented as strong, independent woman. They may put up with McGill's s*** once, but should not really be coming back for seconds after he continues to sleep around. It is just entirely unrealistic.
To be entirely fair, *none* of the characters are particularly deep. But the women stand out as being especially bad. The women are written as characters without an ounce of self-respect, and keep flinging themselves at the main character. As well as sniping at each other for taking "their man".
I'll try out the next book, but I fear it will be another 300 pages of the author living vicariously through his main character's sexual gratification.
