Is it official that there will be no new New Frontier novel? The novels were fun, but the last ones haven't been that good.
I really liked SCE, but I haven't read all books yet. So no reason to miss it.
Vanguard was great. I finished it only recently. It's sad that it's over, but with next year's start of Seekers and the return of some of the established characters, I don't think I will miss it that much.
The same is true for the Mirror Universe saga. The characters and stories were all pretty cool, but I think the conclusion was okay and there is no need to tell anything else.
I didn't read Stargazer or Gorkon, so I can't say anything about these.
