On the cover of Harbinger, it says "Inside: Bonus diagrams of vanguard station". I finished reading the kindle version of this book yesterday, and there were no diagrams included in that edition, despite still stating this on the cover. Are these diagrams available online anywhere?
Right now I'm just hoping we'll get something similiar for the new DS9. *EDIT* Probably not. I remember seeing DRG posting a picture on his fb-page of the actual novels. It says nothing on the covers about a fold-out or something for the new station.
