Firstly, this book was awesome.
Secondly, here's the information I was looking for in reviews while I was undecided about buying. To be absolutely clear:
Yes, this is a reverse harem with bat men who are each more alien than the last.
No, none of the heroes cheat on her.
Yes, there is a happily ever after.
I'm a fan of Jeanette Lynn, and I liked Of Another Dimension and Bridal Hunt, but was disappointed by Bride of Glass (too muddled). Sure, the editing isn't perfect, and at one point I had trouble keeping all of the characters straight, but the story of What Dwells is worth it. No one writes reverse harem like Jeanette Lynn, and this could be my favorite of hers.
SUMMMARY (without spoiling too much):
Novara falls from the sky and is rescued by bat guy, Citoc, and they get steamy quickly.
She's taken to a cave city of bat people--who come in different varieties of colors, shapes, sizes (and I do mean phallically, too, once the reverse hareming gets rolling). As this was where the sample left off, I was worried about mysoginistic practices of this society, but that's not a problem.
For the first chunk of the book she is with Citoc, and they have a tumultuous relationship. Very bantery and angsty in the true Jeanette Lynn style.
I'm a sucker for the books where the hero does something to break the heroine's heart (but doesn't cheat on her, though it may seem like he does). Suffice to say, there's a separation. (There will eventually be groveling.)
There is a threat against Novara's life by one of the other bat people. (Enter villain.)
Insert Harkyn, who has crippled wings. He's the sweet, nurturing hero who always complements Lynn's harems. Their romance is endearing, soul-matey, though not without its heart aching difficulties. (Can't get enough of this tear-jerking section.)
Lynn also provides her trademark "waits in the wings" (pun intended) hunter hero, who has been quietly watching, craving, and wanting his turn with the heroine, whose patience will pay off.
And then there's the HUGE surprise of the fourth hero. (Also cue a lot of action, gore, near death peril, more so than Lynn's typical book.)
Novara's first few scenes with the huge guy are what catapulted this book into being my favorite. I will not spoil who or what he is, but did anyone watch the 1989 Fantasia? If you like big scary monsters having their way with the heroine, sign yourself up for this. And read it all the way to the end.
In the best ways, this book is over the top hareming, over the top weird alien erotica, and over the top "you are mine and we were meant to be together" "I would die and kill for you" declarations of romance.
