This one is more PNR to me as the romance features heavily. 
 It took me awhile to get into it. I enjoyed the bits of Gullah folklore that were peppered in - would have loved to see more of that. The side characters were fun too. I also love Savannah as a setting - its a city I've always wanted to visit. 
 It's kind of like Twilight, except the heroine is in her 20s, there's no werewolves, and she has a past - she was a wildchild junkie in her teens, but sobered up to care for brother when her mom died. The venemous vampires and the "intoxicating rare blood type" made me chuckle. So too Eli, her love interest, who keeps telling her that he is too dangerous. He has a vampire family as well. 
 She gets mixed up with the vampires because her brother lets loose a pair of murderous vampires. He starts becoming a vampire, and Riley needs to save him. I kind of think that the book might have been more fun action-wise to have been able to see part of the story through her brothers eyes as he started changing. 
 Didn't like that Riley had to keep insisting she was a "badass". A few too many unanswered questions. (view spoiler)[That Riley was knocked out so we don't even know about the end of the fight or what really happened to Seth bothered me. (hide spoiler)] 
 It interested me enough that I'll check out the next one.
