I figured there would be too much going on, too much world building (Liz Maverick's Crimson City comes to mind), but I was wrong. This book has a nice balance between, world building, character development and storytelling.
If there is one thing I normally dislike, it's the "soul mate" theme that permeates a good part of paranormal romance. So when in the prologue, our werewolf hero scents his soul mate I thought, OH NO. Ah, but it's okay, somehow Kresley Cole overcomes my aversion to this. The prologue reads like a horror novel--Oooo, I like that.
In fact the next several chapters read more like horror than romance, I really like that. I've always thought that's one of the biggest thing paranormal romances lack. Shouldn't books about Vampires, Werewolves, Ghosts... be scary?
Our hero is a werewolf, our heroine a vampire/valkyrie mix, different races that hate each other. He has spent the last 150 years being tortured by the "Vampire Horde". She is a sheltered young (72) miss, protected her entire life by her Valkyrie aunts.
At times, I honestly thought the hero was on the verge of rape, and yet, as the story progresses, he comes more and more under control. At first you think, our heroine is going to be weak. Ah, but she's not, as the story develops, she gets stronger and stronger. And it all flows nicely together.
I'd recommend this one, and that comes from someone who is incredibly picky when it comes to paranormals.
