There is a lot of violence, and it's a very original take on the vampire genre, along with other supernaturals, but the sex is used sparingly, but the violence is not. But it's a very compelling set of books and I was a bit bummed when it ended. This is a series of 6 books, and all of them are good reads.
Nightwalker (Book 1 in the Dark Days series)Jocelynn Drake
For centuries Mira has been a nightwalker—an unstoppable enforcer for a mysterious organization that manipulates earth-shaking events from the darkest shadows. But elemental mastery over fire sets her apart from others of her night-prowling breed . . . and may be all that prevents her doom.
The foe she now faces is human: the vampire hunter called Danaus, who has already destroyed so many undead. For Mira, the time has come to hunt . . . or be hunted.
These books follow Mira - a nightwalker who's been around for centuries. She's a hard core enforcer, with the elemental ability to handle and manipulate fire, which is unheard of in the vampire realm.
A long time ago, a group known as the Naturi, captured and tortured Mira, trying to steal and control her powers - whom if left loose, will destroy both humans and vampires. But a triad of powerful vampires saved Mira, and now the triad is broken, and it's up to Mira to save the humans and vampires from the Naturi. But there is a human vampire slayer, Danaus, who has been hunting Mira. But Danuas and Mira have to team up to stop the Naturi for the good of the world, with the understanding that they will get back to "killing each other" when they are done with the mission.
It's best to start at the beginning of the series and read through, as you learn that Danaus isn't entirely human, and more and more about Mira's past and what has turned her into what she is today. All the books are excellent reads, and keeps a good pace. There is a lot of violence, the books are packed with graphic violence - there is a bit of romance for the romance lovers out there, and a lot of mystery, suspense and secrets. Good all around paranormal series.
