(written from a Production point of view)
While in the comics industry, she wrote issues of "Critical Mass", "Doctor Zero", "St. George", and co-wrote "The Punisher/Captain America: Blood and Glory" in 1992. She worked at DC Comics, primarily as an editor from mid 1989 until early 1996. During that time, she edited DC's Original Series comics (editing all of the issues from #59: "No Compromise Part Two" through #80: "The Chosen Part 3: Collision Course!") and Next Generation comics (editing every issue from #56: "Companionship" through to #80: "The Abandoned"), plus the Star Trek: The Next Generation - Ill Wind mini-series written by Diane Duane. While working on the line, a number of the artists and writers on the two titles were alienated by Clark.(citation needed • edit) It were not only these authors that had problems with Clark; Rick Sternbach was not a Clark fan either, expressing doubts about her editorial qualities in regard to the by him coauthored Star Trek: Deep Space Nine Technical Manual, as he deemed her text editing had "dumbed down the tech nature of the book". wbm Previously, Sternbach had already stated, "I'm not inclined at the time to work with them, due in part to the editorial differences of opinion I had with them over the 1701-D blueprints and DS9 TM."  Clark also brought Rachel Ketchum onto the TOS line as the primary pencil artist during her time as editor.
Clark joined Pocket Books as an editor in 1995. Working on a number of different licenses, she was initially responsible for the Star Trek line's reference works, her role expanding into editing the fiction lines in 2002 with the Star Trek: Enterprise series, and later with Next Generation novels set after Star Trek Nemesis.
Following the departure of senior editor Marco Palmieri in December 2008, Clark took over principal responsibility for Pocket's Star Trek line. However, as a result of further downsizing by Pocket parent company Simon & Schuster – or rather the gutting of the entire Star Trek franchise by its parent company CBS Corporation – , Clark herself was let go in August 2009, although she was later retained on a freelance basis, working on the Star Trek: Ships of the Line calendars amongst other projects, but not before becoming previously alienated with its two original conceptual authors, Adam Lebowitz and Robert Bonchune, both of whom she replaced with Doug Drexler as chief editor after the first three outings in the calendar series. With Drexler, Clark did develop a warm working relationship. wbm
