An experienced editor who has worked on numerous comics projects, Bennett is perhaps best known for her work with her husband, artist/writer Paul Guinan, and their creation, for Dark Horse, of the Heartbreakers sci-fi action series. Bennett and Guinan also collaborated for their contribution to the Aliens series: Aliens: Advent/Terminus. Guinan was also one of the main creators behind the Aliens: Colonial Marines comic series that ran from 1993-1994.
Bennett also served for a time as a popular editor of Dark Horse's Star Wars comics line in the early 1990s.
- Known for being a particularly good-natured comics contributor, Bennett has made a number of "cameo" appearances in the comics she's worked on, and this has extended to the Aliens comics line: she is ripped in half by a Xenomorph in Dark Horse Presents #42.
