Dayton has posted about the cover of That Which divides on his blog:
It was brought to my attention earlier today that Simon & Schuster has updated their online catalogues with several new book covers, including a handful for upcoming Star Trek titles. Among the new additions is this VERY MUCH NOT FINAL cover for our forthcoming novel, That Which Divides.
The reason I know it's not the final cover is because I saw this image a couple of weeks ago, and was asked for my input. I provided feedback based on info from the actual manuscript, which the cover artist didn't have at the time he created this interim image. He was working from some pretty basic info provided to him by my editor, and given what he had to work with, this is actually a pretty slick image. My feedback was aimed more at tweaking the image to bring it in line with the events from the manuscript this is supposed to depict, and to "juice it up" some. I'm still waiting (and excited) to see what he brings with the next go-around.
