Sherrilyn Kenyon - Retribution

A hired gunslinger, William Jessup Brady lived his life with one foot in the grave. He believed that every life had a price. Until the day when he finally found a reason to live. In one single act of brutal betrayal, he lost everything, including his life. Brought back by a Greek goddess to be one of her Dark-Hunters, he gave his immortal soul for vengeance and swore he'd spend eternity protecting the humans he'd once considered prey.
Orphaned as a toddler, Abigail Yager was taken in by a family of vampires and raised on one belief -- Dark-Hunters are the evil who prey on both their people and mankind, and they must all be destroyed. While protecting her adoptive race, she has spent her life eliminating the Dark-Hunters and training for the day when she meeting the man who killed her family: Jess Brady.
Jess has been charged with finding and terminating the creature who's assassinating Dark-Hunters. The last thing he expects to find is a human face behind the killings, but when that face bears a striking resemblance to the one who murdered him centuries ago, he knows something evil is going on. He also knows he's not the one who killed her parents. But Abigail refuses to believe the truth and is determined to see him dead once and for all.
Brought together by an angry god and chased by ancient enemies out to kill them both, they must find a way to overcome their mutual hatred or watch as one of the darkest of powers rises and kills both the races they've sworn to protect.

Comment: Each new book by this author is like a ray of hope in the fans. We always expect that this is the book that will bring more news about the world we love so much.
However, this one brought even more questions. As usual.
I understand the need of the author to explore to her maximum all the ideas in her head, but to be honest, there are so many things happening at the same time, so many pantheons and gods around that it's getting difficult - even for someone who has read the books from the beginning - to get in mind all the facts and names and beings and stuff.
I wish she would solve some things along the way, in order to make the world evolve. Things happen here, happen there but I don't see much link between everything and at the rhythm she can follow, I don't know how old I'll be when the series finally end.

The story. Of course I enjoyed knowing more about a whole different pantheon, I'm indeed curious to see where this will go, especially since, apparently, the new DH book, coming out next year, will follow this one.
The romance was good, I liked seeing them together, but I think the way the story was presented, that everything happened too fast, and honestly can you get in on when surrounded by wasps and there's the danger of them reaching you?
Anyway.
This book presents a new pantheon, like I said, and with it, new myths and legends. What I found interesting in the middle of all the new information is the roles both Jesse and Abigail have. Didn't see it coming and if, on one hand, it's amazing to see the author's freshness of ideas, on the other it just complicates all we know and there we go again to that not-solving-things-at-the-moment thing.
What I really enjoyed was to see some characters from previous books. Always a pleasure.
Also good was the bonus scene at the end of the book, where we see Tory having her baby. Wonderful to see that scene and even better to see Ash living though it with people who love him, *sighing*
Next month is released another book in the series, although labelled dream-hunter. To me it's all the same thing, as everything is connected one way or another, so I wish/hope to see something new happen, something solved.
