Good, right up until the last book, which falters a little.
For those who don’t know – and there’s no reason that you should – the Star Trek spin-off books set in the post-Next Generation time frame have, in recent years, ended up re-casting the franchise as more of a political thriller/Cold War allegory than has previously been the case. The End is the culmination of this trend, I suspect, a five-book series that ties up all manner of plot points and loose ends more-or-less satisfyingly, and clears the way for a relaunch of the major franchises involved.
The last book in the series suffers from, well, being the last book in the series, really; there’s a lot that has to be revolved and explained, and the writer was either left with an out-of-nowhere plot twist that everyone else had stayed away from or something that he invented himself in order to give his book something that wasn’t just spill-over from the earlier entries in the series. It’s an odd choice – I’m trying not to spoil it – that could have worked if it had at least been hinted at earlier, but appearing as it does when it does, it feels tacked-on and problematic.
But overall! I liked the series, in large part because I liked Star Trek: Cold War In Space as a concept. If they really do go back to the traditional exploration mode that the final novel hints is an option, I can’t tell if I’ll be disappointed or not.
