First, the cover design rocks. I was one of the people who thought this was a paranormal romance, but it's more of a science fiction mystery. It's a darker story about an alien hunter, Mia, who has to work with a dangerously attractive -- and plain dangerous -- alien because her partner will die if she doesn't. It's one of those who-do-you-trust? stories and I liked it a lot once I got into it. I was reminded of the politics of non-humans vs. humans in Charlaine Harris's novels.
