I worked in a tangential industry seventeen years ago when I wrote the first draft. The FDA approval process has changed since then, but the premise of the book still compelled me. I knew enough to be dangerous and had a few contacts who helped me get the research right, and when I looked at it many years later I still really liked the storyline and decided (at the time) to “dust it off, make a few minor changes,” and seek publication. What happened instead? Essentially a massive rewrite of the story including the title, even though the overlying idea remained consistent.
