I like Beyer's book, have enjoyed them.
I guess the major problem I have with them killing Janeway off is that it was written by an author who has stated he never like the series. If you didn't like the series why write for the character? It added insult to injury for me to have him write her death, even if he handled it well in the general opinion of most.
But as others have stated I can blissful fall into fan fiction, and some damn good fiction at that, where the story is to my liking and makes me feel happy, happy, joy, joy.
