(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) 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, 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.
