I am precisely the kind of hypocritical little brat who would dismissively call this "Twilight for Academics" while raving about another author writing a queer Fifty Shades retelling.
And, like, granted, part of that is everything is better when queered, which sounds glib and is untrue but often I find that the queering of narrative brings the fissues of heteronormative assumptions to the surface and makes the author grapple with, in particular, questions of dominance and gendered assumption of power. If the maiden and the vampire are both women...okay, fine, then it's Le Fanu's Carmilla, but that's already an interesting text. What makes that move so compelling is that it calls into question the whole conversation about  love as possession and the attraction of dominance and power and the inherent animalism which is actually paternalism that frames the vampiric desire to own as good, actually.
If you have to negotiate that without the stereotypical gendered component, I think it can be more interesting. 
(And if these authors ever in their lives read an accurate depiction of kink and consent, it could be a MUCH more compelling story.)
Which, I think, is where this book lets itself down. It's interested in the trappings of academia without engaging in the academy's larger critiques of power. It's like Diana is constantly pushing against Matthew's actually pretty reasonably boundaries around his own feelings and completely unwilling to engage with the way he fails to respect hers.
Like it's fine, I enjoyed it, it was a good shabbos afternoon, but it doesn't have anything interesting to SAY. This is a book that thinks "preventing people (even if creatures) from loving those of other races" is a radical rallying point and I just have a hard time getting excited about fantasy that thinks Love is Love is an interesting thought experiment. I think I am not the right audience for this book, which is also worth noticing because I wonder if I would have been had I read it in high school or college, back when Rochester was a character I was willing to defend rather than appreciate.
