I thought the book was a really average read. I really, really dislike the idea of bringing back Janeway and I would agree with the opinion that her relationship with Chakotay feels really, really forced. I just can't picture the two of them together.
I also felt the book relied on too
many twists and turns. I liked Eden and I'm disappointed Janeway will (likely) take her place in the Delta Quadrant fleet. I wish Janeway would've remained dead. Hell, I would've been pleased had Junior tried to bring her back but ultimately failed.
