I'd be interested in seeing again:
Phillipa Louvois (TNG "Measure of a Man")
I always liked her, too. She did show up recently in The Buried Age
, which takes place a few years before "The Measure of a Man," and deals with Picard's court martial. I don't recall her showing up in any other novels, but she did appear in a couple of issues of DC's TNG comic, written by Michael Jan Friedman. It was a kind of cool story about her and Data.
Peter Kirk (TOS "Operation: Annihilate!" and novel Sarek
I'd to see more Peter, too, but as much as I love Sarek
, I somehow doubt contemporary novels would jibe with that portrayal of the character.
