I really hope she's not back. Not because characters should stay dead(still hoping for a data return!), but simply because I can't stand the character. Some of the things she did in the series, and particularly in Endgame pretty much made me unable to stomach anything involving her. I still kept away following Before Dishonour simply because most of the crew is so incredibly bland & boring, but Beyer's books got me into it again, although mainly due to her own characters.
Hopefully even if she does return she's off to the alpha quadrant as soon as, or dies again(I'd pay to see that...again!).
