Let's see, this thread is for listing connections between/among novels, right? Well, I just discovered a minor, unexpected one. In Howard Weinstein's first Trek novel, The Covenant of the Crown
from 1981, there's a brief but memorable appearance by a security guard named Ensign Michael Howard (possibly a self-insertion, judging from the name). The same character (or a character with the same name, rank, and posting) reappears eleven years later in Ice Trap
by L. A. Graf, and again in at least one other Graf novel, Firestorm
. There's also a very brief mention of a security guard named Howard in my own Ex Machina
, which I intended as an allusion to the Graf novels, but I'm pleased to discover that Ensign Howard originated in Covenant
, one of my all-time favorite "oldies." And surprised to see that L. A. Graf were able to include that reference in a time when the books were supposed to avoid continuity and crossovers. I guess he's an obscure enough character that he slipped under the radar.
