Reflections in a Shattered Glass by Joe Nazzaro, illustrated by Susan Lovett, 1989.
Oh my god, where to begin? Yes, it’s written by a fan who went pro, and illustrated by a fan art legend. It had the full approval of Terry Nation, who wrote the forward for it. For all that it’s a typical stapled booklet fanzine, it’s professionally typeset and printed. And the story is absolutely amazing.
A freak teleport accident sees Vila and Avon transposed with their opposites in an alternate reality. In this mirror universe, Blake is the Federation’s top agent, running a crew of the most vicious psychopaths on the Vanquisher II, a captured alien vessel. Their mission is to obliterate the resistance wherever they find it, and now they are seeking the leaders of that resistance: Travis and Servalan. Vila and Avon are hard-pressed to keep what’s happened a secret while they simultaneously try to get back while avoiding being casually murdered by their crewmates. This is complicated still further when they discover their counterparts are actually resistance themselves, putting them right in the middle of the madness.
There are fascinating character differences in here with the alternates, which alone would make the story worth it. Vila is a tough, sarcastic brawler, always ready for a scrap, and Avon is meek and mild. Travis is honorable and levelheaded, Servalan kind and caring. Cally is a full telepath, and like all the Auronar, a spymaster for the Federation (predating Psi-Corps by 5 years!) Gan and Jenna are vicious, conspiring killers. Blake is a terrifying, cold maniac (and the sole reason the crew haven’t killed each other long ago.)
Our “heroes” are disturbing, the story is memorable (if a bit soul-scarring at points) and the interior art is amazing. If you can find it, get it.
