Nothing to write home about. I'm not too clear on the worldbuilding here and don't feel the like the author let us in on anything. Everything is mystery after mystery; we're thrust into Kate's life and don't get to know her. I might read the next in the series just to see if it gets better, but I'm not hard-pressed to continue with this one.
The writing is good, I can't say it isn't. The story flows but seemed a bit choppy in spots. I like Curran and I'd like to have seen him and Kate battle it out just to have it done with. The start was really slow and it took me way too long to finish such a short book.
