Working together, the pair combined Ordover's ability to arrange pitch meetings with the shows' producers with Mack's training in screenwriting.

A few weeks later they made another sale, this time to Star Trek: Deep Space Nine, for the fourth-season episode "Starship Down".

[3] Mack and Ordover wrote the four-part Deep Space Nine/Next Generation comic book miniseries Divided We Fall for WildStorm.

With Keith R.A. DeCandido, Mack co-wrote the two-part Starfleet Corps of Engineers (SCE) e-book story Invincible.

Mack also wrote Harbinger, the first volume of the Star Trek: Vanguard novel series, which he co-developed with editor Marco Palmieri.
