Although I own a Kindle(it's in a drawer somewhere)I dislike the idea of e-book only releases.
Okay if the stories are collected and released later in paper form but that doesn't appear to be the intention of Pocket.
This. Especially for stories that are integral to the continuity of other stories that HAVE been published on paper first.
I don't see why that should matter. With the possible exception of two-parters, it's not like you have to read every novel to understand what's going on in others; they're all designed to be readable by themselves.
1. How do you feel the Trek book line has done in the last 12-15 months?
Overall, the line seems quite healthy to me. There are some choices I didn't agree with, and some novels I'm not interested in, but I'm generally satisfied with the direction it's going in. And I'm glad they're still doing politically-oriented, post-series 24th century novels, even though those apparently don't see as well as TOS 5-Year Mission stories.
2. More specifically, what have you liked in regards to the entire Trek book line in that time? What were your three favorite Trek novels in that time and why?
My favorite novels published since January 2012, in no particular order, are:
Storming Heaven by David Mack
Plagues of Night by David R. George III
Raise the Dawn by David R. George III
Brinkmanship by Una McCormack
Silent Weapons by David Mack
3. Now, what did you disliked regarding to the Trek book line of the last year or so? What were your three least favorite or disappointing books and why?
I didn't agree with the decision to resurrect Janeway, or to create the Data 2.0 copy in
Cold Equations. I haven't read
The Eternal Tide, so I only know that I disagree with the idea in principle, and have no opinion on the quality of the idea's execution. I thought David Mack executed the idea of "resurrecting" Data brilliantly and that the trilogy was very well-written, though I still disagree with the resurrection in principle.
I did not enjoy
Fallen Gods by Michael A. Martin, though I didn't think it was quite as awful as many did.
I did not read any other Trek novels that disappointed me. I have a good sense of what Trek novels I will probably enjoy or not enjoy, and I generally avoid the latter.
4. What new recurring trends or themes in the last 12-15 months have you picked up on?
There's certainly a stronger emphasis on standalone 5-Year Mission TOS novels, presumably because of TOS's broader market appeal. I have no problem with this, even though I'm rarely interested in such books, because A) this presumably helps support the entire
Star Trek line, allowing for more niche taste books to be published, and B) it means I have more time to read non-Trek stuff and needn't develop as big of a Trek backlog.
5. What editorial decisions from the last 12-15 months have you like? Disliked?
See above re: resurrecting Data and Janeway.
I wish the current editors would start hiring Keith R.A. DeCandido again. In particular, I think his authorial voice is an excellent match to TNG.
It hasn't been published yet, but I'm glad to hear that the ENT line is being resurrected and that they're focusing on the early Federation era.
6. What would you change in the Trek book line? Everything? Nothing? Be it production choices (artwork, type of book) or story editorial decisions?
Some of the book covers haven't been great, but that's not why I read Treklit.
See above re: KRAD.
I'd love to see more stuff from Una McCormack -- and apparently, I'll be getting my wish with
The Fall. (Incidentally, it was the combination of Una McCormack's praise and the release of the film
Tinker Tailor Soldier Spy that got me into John le Carre recently, and I'm devouring his stuff. Thanks,
Una!)
Always glad to see more stuff from David R. George III and Christopher L. Bennett.
My reaction to David Mack's novels: "MOAR!!1"
I'm always interested in Trek stories with a political bent (preferably a leftist one), and in particular those that focus on the Federation government and society.
The Fall sounds like it will deal in part with some of that (Federation politics, anyway -- I doubt there will be much that's explicably leftist

).
One thing I've noticed: The regular staple of Trek authors these days is mostly white guys. Nothing against white guys (being one myself), but I do hope that Pocket makes an effort to create author diversity going forward.
And, of course, I wish Marco Palmieri were still editing the Trek line.
