Honestly, I don't know if I will read them, too many good characters gone and replaced by (for me) uninteresting characters. The comparision to the excellent seasons 1-3 books will be to a clear disadvantage for the current books.Kes occasionally comes up in the relaunch novels for a page or two. She even has/had a son.
Are you sure you're not going to read them? Anyway, SPOILER WARNING!
Captain Eden will be head of the Voyager Fleet (9 ships altogether with Voyager taking the lead). Their mission: to go back to the DQ and find out whether the borg have really vanished from the galaxy. But Captain Eden is tortured by visions on this quest and for some inexplicable reason she feels that she has to check out that piece of rock which Kes and Zahir visited together. She can't explain it but she definitely knows that what Kes saw on that journey is a map ... and an incomplete one at that. So she has to find the missing pieces of the map - and learn secrets about her own past no one could ever have imagined. Least of all she.
Will this do for an explanation?
When it comes to Kes, I prefer my own stories.
However, I will give Beyer some credit for not ruining the character Kes and for bringing Janeway back to the Relaunch Books.
But who knows, I might read the books some day in the future
