Trying not to judge this too harshly since I'm not sure of a romantic to begin with. Some of the ideas were cool. I liked the tattoos on the slayer. Was excited to see an incubus but wished for me from him.
The thing that ruined this for me was how annoying Violet was. I mean, she was on her back in bed most the book and feel in love with everyone that slept with her. I didn't buy the I'm in love with this guy then hours later fall in love with another. I like it much more when characters have a backbone and brains.
