I had a book which claimed to be a collection of tentative episode plots for a fourth Star Trek season. It seems very little known, I've never seen it since. I remember it has two 'authors' who were involved in the original series, vouching for the book. I misplaced my copy and forgot teh 'authors'. Can anyone help me find the title of the book again, and then I can see about buying a replacement? The book was plausible, with new Star Trek stories.
