I just saw that TrekWeb just posted the Amazon describtion that we are all talking about on here. Makes you wonder more about this whole thing.
I bet the Columbia got sucked into some kind of anomaly or wormhole that got her stuck in the Gamma Quadrant somehow. I'm sure Mack will explain that in the book.
I know for sure like you all, I can't wait for this book either. I have to figure out how to try things in w/ my on going series I'm working on, which will all be revealed in fan fiction and the art section as well. I have made some posts a summer or so ago about it.
