Snaploud, I'd say that's a pretty phenomenal list you've got there. Just about every single one of those books I'd rate a 9 or a 10 out of 10. (The only one on your list I really didn't like was Titan: The Red King, and opinions there vary.)
It's really fantastic how much good treklit there is these days, isn't it?
argggh.. don't tell me that; that's the book I'm getting ready to start! I finished
Taking Wing today and I actually liked it quite well. The ending left me looking forward to
The Red King. What didn't you like about it?
It has a reasonably good set of plots, but they only involve Riker, Tuvok, and a bunch of guest characters that leave at the end of the book. That is, we introduce this whole new amazing cast of aliens, and almost all of them are literally useless for the whole story.
Plus, I think they got a cute idea for a story, the whole Red King thing that the title refers to, and were so proud of it that they explained it all right at the beginning without allowing any mystery to build up, and the explanation itself required so many reams of bizarre technobabble that it just lost me entirely.
So, I didn't buy the concept, I thought the book gave up its secrets too early, and it didn't do anything with the "leads".
Really, considering what the mission statement of the whole Luna thing was supposed to be, I'd consider Orion's Hounds the real first book in the Titan series. The other two are an odd extended prologue that fix a whole bunch of other loose ends and nonsense, but really have almost nothing to do with the cast of characters & purpose of the series as a whole. (But at least Taking Wing had all the Romulan politics, which I thought were interesting, going for it. Red King? The gimmick fails, so the novel does too.)
