A season for slaughter

For once we get spared the indoctrination lectures. Don't worry, the levels of annoyance will be kept up by our main couple being all love-y-dove-y.
To be honest, it felt like the author is finally starting to get a bit of a hang of this writing thing he's supposed to be doing. Kind of. Maybe. Sometimes.
I liked how the sting-fly and helium thing was set up. Best bit in the whole series, the reveal.
I think I might have liked this book best because it had more on how the invasion is going than previous ones.
