I liked Resistance and Before Dishonour. The former being a borg attack and the latter being the reprecussions from it. And then Greater Than The Sum being the reprecussions from the reprecussions.
WHAT?!?!? Before Dishonor was far from just being the repercussions of the previous book. And it in fact did have quite a large Borg attack of its own. Larger, IMO, than any other Borg attack we've seen to date.
But it wouldn't have happened had the events of Resistance not happened. Like how had Q not introduced the borg to the enterprise, Wolf 359 wouldn't have happened.
And yes, i liked Before Dishonor, despite it's comical nature, half-arsed mutiny and a pirate-type character similar to Xyon. I liked it.
