BTW, I'm ignoring the labeling of my previous post as "feminist." I am a female and have my point of view, but I'm not playing the gender card, honest.
Except you did. Because if you want us to disregard gender then your entire post becomes "They killed my favourite character, so I'm not buying any more books in protest". And honestly, I get that. I can emphasise with that and I can understand absolutely why you'd be pissed off and want to complain on this message board. And from a story perspective, I get why you might think it was a bad choice. Though given their past record, I'm willing to give Pocket's editors and writers the benefit of the doubt in terms of knowing what they're doing.
But you're trying to leverage gender issues to explain why she shouldn't have been killed off. And that gets dangerous. Because it swiftly becomes "Janeway shouldn't have been killed off as she's a woman". In other words, suggesting that her gender should get her special treatment. Janeway wasn't killed off because she was a woman so it shouldn't matter (if anything she was killed off because she was an Admiral and so hard to write into future stories, or maybe they wanted to kill off someone big and Voyager was the least popular show).
If the writers and editors decided that, "hey we have a great plan to really shake up the books and allow some brilliant new story ideas and such: we have to kill Janeway" but then went, "oh no, best not, she's a woman. It'll upset the feminists". I'd be narked. And you should be too as it's gender inequality at work.
But the only way your arguement works is if Peter David turned up drunk at Margeret Clark's office one day and went: "Oi! If you want me to finish this book, I'm going to kill Janeway. Because I hate women. And if you don't, say good bye to your TNG re-launch bitch". Unless you seriously think Janeway's gender was a motive for Pocket in killing her off then the fact she's a woman really has nothing to do with it.
And it's a shame you'll be stopping reading the books, such as October's Destiny Trilogy which features Captain Ezri Dax and Erkia Hernandez (probably) in crucial roles.
