Haven't read it yet, but I understand it's the culmination of the Mirror Universe storyline that's been woven through several of the other lines including the DS9 Relaunch. I vaguely recall Kes having a role in one of the MU anthology stories (Obsidian Alliances I think), so maybe it follows on from that. I don't particularly expect you to relent on these issues; you've been dogging the Kes issue far too long for that. But I think even you can acknowledge that you can't give an informed opinion on the quality of the books without reading them. At best, you can express your disinterest in finding out.
