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.
Actually most people think it was very badly done. Even those happy to never see her return and those who weren't Janeway fans. I thought the writing was terrible, much of it didn't sound like the characters at all.. there was no drama or build up. A very poor book which I think contributed to the anger over her death in the first place.
