Though in Dreadnought I couldn't help but think when Piper goes to rescue Kirk and co. And instead find they escaped on their own, that if she hadn't stopped to go on abou her Academy paper no one really cares about she might not have missed them escaping and got left on Vice Admiral nutbag's ship.
Piper is one of the most obvious Mary Sues ever, so it was rather refreshing to see that she can actually mess up.

One Trek book that was a huge letdown and awful as well is Enterprise: The First Adventure.
There were a lot of things off character and the story for the first time Kirk captained the Enterprise was just over-the-top silly.
Yeah, I'm sure the time when the bridge was overrun by a swarm of POODLES was not exactly a high point in Kirk's life.
As for horrible books: Anything written by Myrshak & Culbreath. I couldn't even finish those damn Phoenix novels.
