Fifteen years ago saw the premiere of Harbinger, the first book in the Star Trek Vanguard series, which I co-created with Pocket Books senior editor Marco Palmieri.

What was Star Trek Vanguard? Dayton Ward sums it up thusly:

Vanguard as created by editor Marco Palmieri and author David Mack is a series of books that served as a “literary spin-off” of the original Star Trek television series. Running in parallel with the original show, Vanguard was set aboard a space station in a hotly contested area of space called “the Taurus Reach.”

In the years that followed, I wound up alternating writing privileges on the series with Dayton and his hetero life-mate and frequent writing partner Kevin Dilmore. This, among other things, led to them becoming two of my closest friends, with whom I shared the most artistically satisfying creative endeavor of my career to date.

Marco, who left Simon & Schuster after editing the fourth Vanguard novel, subsequently returned to the saga as an author, contributing the novella “The Ruins of Noble Men” to the Vanguard anthology volume Declassified. And acclaimed international best-selling thriller author James Swallow took Vanguard into the Mirror Universe with his short story “The Black Flag,” in the anthology Shards and Shadows.

Furthermore, we had the amazing good fortune that all of our series’ cover art was created by the brilliantly talented Doug Drexler. Every single one of his covers is worthy of being enlarged to billboard size and plastered onto the side of a skyscraper.

Dayton has done an amazing write-up about Vanguard — what it is, how it came to be, and what it has meant to all of us who were fortunate enough to work on it. I doubt I could improve upon it; I would only end up paraphrasing it. So I’ll just say, go read his excellent tribute to this series we built with love, sweat, and imagination.

Dayton, Kevin, and I have agreed that we have no intention of ever re-opening the toy box that was Star Trek Vanguard. From the outset, the saga had been planned with a clear beginning, middle, and ending, and ultimately we hewed fairly closely to that original plan. What’s more, we ended the saga on our own terms, by design rather than by necessity, a privilege one is rarely afforded in the world of media tie-in writing.

Sometimes I daydream of seeing Vanguard as a new Star Trek TV series. But then I remember that it likely would never be as good on the screen as it is in the theater of my imagination, and I’m content to leave it where it is.

As Pennington wrote at the saga’s end, “Let the world forget; I’ll remember.”
