(written from a Production point of view)
Margaret Wander Bonanno (7 February 1950 – 8 April 2021; age 71) was a science fiction author from New York, with over twenty novels to her credit, including several set in the Star Trek universe. These include Dwellers in the Crucible, Strangers from the Sky, and Catalyst of Sorrows.
She rose to the spotlight of Star Trek apocrypha when her novel Strangers from the Sky made the Time bestsellers list in 1985. But the story that gave her more fame in Trek circles was what followed.
She is also credited with writing Probe, though in her words it is "not her novel." She was contracted by Paramount to write a novel she called Music of the Spheres, based on the Whale Probe of Star Trek IV: The Voyage Home. However, due to the undesired intervention of an editor at Paramount, the story was nearly completely re-written without her consent, and they refused to remove her name from the project. 
After this unpleasant experience, she focused on projects other than Star Trek novels, such as the science fiction book Saturn's Child, co-written with Nichelle Nichols.
In 2003, she was interviewed for the Star Trek IV: The Voyage Home (Special Edition) DVD, hosting a special features section entitled "Vulcan Primer", in which she explained a brief history of the Vulcans and why they were so popular among fans.
More than ten years after the events surrounding the publication of Probe, Bonanno was encouraged by fans to contact the editorial team at Pocket again. Although she believed that she had been blacklisted from working for the company, then-editor Marco Palmieri was able to allay her concerns, and invited her to submit a pitch for the Star Trek: The Lost Era series that was under development at the time, leading to the novel Catalyst of Sorrows.

A short story entitled "The Greater Good", written by Bonanno, appeared in the 2009 Star Trek: Mirror Universe anthology Shards and Shadows, while a full-length novel, Unspoken Truth, was released in March 2010.
