Great read. But I have a whole lot of questions and I'm wishing I read the first book before this. And I'm not talking about Astrid and Zarek, it was everything else that made my head spin. The story structuring could have been waaaay better. SK doesn't really waste time explaining all the different demons and sub species which became inherently confusing and hard to follow. Are Appolites and Daimons one in the same? And who is fighting who? This book was busting at the seams with the overcrowding of groups fighting groups and it became very hard to follow who is on whose side exactly in this 'war'. And I'm still unclear about the mortals vs. immortals characters in this and the rules that apply. Are Dark-Hunters immortals once they become Dark-hunters? If so, why the hell was Zarek lamenting over not being allowed to live in Olympus to be with Astrid? He's not a mortal so it didn't add up. And how come Zarek's eyes changed from blue to black? He had blue eyes as a human slave but as a Dark-Hunter his eyes are described endlessly as black. That obvious change was never addressed and kinda drove me crazy. I also felt that there were some inconsistencies as far as character descriptions and physical actions that could have been caught (especially during the sex scenes ahem). I point this out only because I kept catching them and would have to go back and re-read a paragraph or whole page thinking I missed something. The mistakes are pretty obvious and quite a few. Zarek taking his pants off & undressing two times in one love scene, penetrating her without taking his pants off, getting off a snowmobile two times, Astrid rubbing her rump against his erection from behind when she's described as laying down facing him, etc. etc.... This was in serious need of editing. The mistakes and contradictions were everywhere. 
 As for the world building, I could say it's my fault for starting this series from the middle but I've dove into other PR series in the middle and read books as stand-alones and had no problem connecting the dots. No matter what series, authors always give readers slight reminders, cues and nudges as to what's going on in every book and past history and who the characters are. Those slight nudges were completely missing here. It's only the third book and yet Kenyon couldn't bother giving us back stories & character information? Really?? She seemed to kind of cut corners and edit out all the important information and just dive in with dialogue and action. I get for the sake of redundancy she didn't want to but it just made for confusing world and story building. Especially if you have a world this dense and complicated you would think it would be better to remind us who is who and where is where so to speak. Help fill in the gaps. There are a handful of demons, immortals, hunters in here that go by different race names. And half of which all have long blond hair, blue eyes and a towering build. Lord how are we supposed to tell them apart? lol It's clear this is a big series with a heavy ensemble cast with a hierarchy of different characters and realms but IMO the author needs to support her characters and help readers along by being a little more informative. It made my head spin trying to just follow along the old Thanatos vs new Thanatos drama. Omg that was so confusing. 
 I loved Zarek and Astrid. They were sweet, sexy, intense and heartbreaking all in one. Any woman who can bring a man to his knees is my kind of gal. ;) The dreams and flashbacks of Zarek's life as a Roman slave were brutal and gut wrenching. I wanted Astrid to just cuddle up with him and take away his pain. I did enjoy this so don't let my review sway you. I just have a bunch of questions and things I noticed while reading. I love the world created and character interactions. There were a lot of elements in this that I generally gravitate to so I'm hoping to continue with this to see where it goes. Has a lot of potential. Acheron intrigued me the most, he seems the most mysterious and menacing out of everyone. Which says so much considering Zarek was put in complete isolation from everyone and had an awful traumatic life before meeting Astrid. Zarek is very similar to Zsadist I'm almost wondering if SK read the BDB books while writing this character. lol They could be twins. No disrespect to Phury! (love you boo) 
 And speaking of Acheron, for someone supposedly so lethal and deadly and someone Artemis clearly is terrified and in love with, why was he letting her punish him physically every time she would get angry?? It didn't add up. I'm clearly missing something there. I didn't understand how or why he would let her do that when he clearly has the upper hand in brawn and powers. 
 Aside from my nit picking, great introduction to Kenyon's writing. Hoping for more!
