RE: the secret drama surrounded the Reeves-Stevens' Trek books...
I think, IIRC, the Reeves-Stevens were planning their own book (or article?) about their Trek writing, and didn't want to reveal too much in Jeff's book. But when they started working on the "Enterprise" TV show, their spare time got sucked up by that.
Did they do a piece for one of the "Signature Edition" compilations?
UPDATE: Ah, yes, but before 2006. "Worlds in Collision" (Nov 2003) reprints "Memory Prime" and "Prime Directive" by Judith and Garfield Reeves-Stevens, a new introduction by the authors, and an interview with the authors by Kevin Dilmore.
