In Kirsten we trust. If Janeway is coming back, then she'll most definitely handle it with the utmost care. No doubt
I think that having Janeway come back would be a nice and hopeful thing to have happen in a Star Trek universe that has become very dark. It would be nice to have a little bit of light shine in that darkness. I was never the biggest Janeway fan, but I find that I miss her and would welcome her back. Beyer is a master of VOY so far so I welcome her bringing back Katherine Janeway in this new book.
