Quite frankly, considering that it is just over 3 months out from the planned publication, I start to wonder if the next book is even going to become a reality. Especially if one considers the fact that practically nothing can be found about it, except a suggested cover.
I wonder if the author is sort of running into a big fat dead-end with all the plot holes he digged in BTRW:
a) The Vulcans have practically been character-assasinated with their flat-out abandonment of their allies. Their general secrecy and flat-out deception throughout all of the relaunch universe does not the least live up to, what T'Pau promised at the end of "Kir'Shara"
b) Andoria and Tellar are tucking tale, too

With allies like that, how did the Federation ever come into being? This lot makes the EU look like an efficient and reliable bunch.
c) most NX's either disappear or are lost before they are really out on the battle field. Are Erika and Archer the only captains in Starfleet that can tell their own arse from a hole in the ground?
d) The latest fad in the Trekverse seems to be: "How can we torture Vulcan this time?". While Martin was "content" with just killing Suraks katra, practically beheading Vulcan, the thugs, who wrote this godawfull Reboot junk opted for a complete blow-up of the whole damn planet. Thanks god there's no uppance for that, or the next book would have taken that pissing match to epic proportions.
All in all (except d) my peeves with it, make it hard to imagine, how the author is going to go from there.
I also noticed something about the "cover" that's floating about. It doesn't really fit in with earlier covers. The one for BTRW had T'Pol in Starfleet blue and looking a few days older than in the show. The new "cover" shows her back in one of those whorish catsuits and Trip back in Starfleet blue - isn't he supposed to be butchered to look like a Vulcan? Unless they are going to whack LFM with a reset-button the size of Belgium, it has already been established that Trip never pulls an official Lazarus. I think the one "cover" floating about is a creation from fandom.
I have serious doubts that the book is going to come in october (if at all) and even if it does, I'm not so hopeful about its potential story-line.
