It's good but not great. Regardless, I did actually enjoy the book.
It's a paranormal romance and as such, it follows the formula all too well. Unless this is your first foray into the land of PnR, you know basic storyline.
"Loner/surly supernatural creature meets plain jane and they fall madly in love. Snarky humor, angst, bad guys to defeat, personal issues to overcome, and of course a happily ever after (or at least a happily for now)."
However, that doesn't mean that it is a bad formula. It's all in the execution, not the skeleton. Damsel (mostly) wasn't in distress and she does some rescuing of her own. The good guy vampires are unbelievably hot alpha-males but all organic and eco-conscious. That's not a bad thing for me but, I'm a bit of a hippie so its all in your perception. I did like our heroine although she's not in my top ten favorites or anything.
It was good enough though that I bought the second and the third in the series although not so good that I've read them yet.
