I love a good urban fantasy with a dash of darkness and mystery. Kian is a charming fellow, and it's easy to like him even though he is objectively kind of an ass. Rosemary is an easy-to-like gal, but sometimes she is a little boring in her sticklierness. The two of them balance each other out well, I think. Also, the magical theories and ImplicationsTM of how magic works in this world after the whole dragons-tooth-warriors and skeleton dinosaurs thing (and honestly, after the microghost diseases) is going to live RENT FREE in my head for a long time. Oh, and the living skeleton is always cool.
