Most of Martin's works have been written in collaboration with partner Andy Mangels, who brought him aboard as a co-writer in 1997 for the Star Trek: Deep Space Nine comics at Marvel. Together, they concluded the events of the cult-hit television series Roswell (which had ended in somewhat of a cliffhanger) in their books Pursuit and Turnabout. He also collaborated with Mangels on "Stolen Heart", a short story for Tales of Zorro, edited by Richard Dean Starr and published by Moonstone Books in 2008.
Martin has worked with Mangels on the Enterprise relaunch novels. Three were written together, but the fourth, Beneath the Raptor's Wing, will be written by Martin alone. With Mangels as co-writer, Martin has also written eight other Trek novels, and multiple short stories.
