I'm not too sure of what to say. It's a good finish for an interesting prequel series. The story is creative and especially grounded for a sci fi story. Perhaps my lack of satisfaction reflects more on the lack of growth I am finding in these books.
-Overabundance of time spent on explaining universe setting minutia that series veterans have heard a dozen times
-Villains who are hypercompetent at skullduggery but always incompetent at a stand up fight
-Heroes being saved by a bit too conveniently coincidental twist that they couldn't plan for
And this series had a bit too much romance melodrama for me to handle.
I find myself less enamored with the Fleet series. I feel like I'm just reading the same book again and again just different places and sometimes different names. It's not bad, just...too much of the same.
