Poor Data (B-4). Trip, Spock, Kirk (and maybe in future Janeway?) all come back from the dead but Mr. Data isn't allowed to.
I'm a little surprised (and discouraged), that no one has adressed the fate/future of Data in a novel (i.e. somehow escaped/taken at the last split second).
This is science fiction, and any number of possibilities could be used to bring back one of Trek's most popular characters. He could then very easily live on in future books.
Unless there is some type of novel review board at Paramount that will not approve this type of storyline.
