Its a great concept - ghosts as a species - living only through possession of humans. The first person narrative works very well for it. It allows you to sympathize with the ghost before the implications of what the ghost does in order to live really sink into your thoughts. Your first impulse is that the ghost is the hero/heroine of the narrative and so those who seek to destroy it are the wrong - or are they? As the book weaves it's narrative, we start to recognize the slivers of righteousness associated with the assassins. We start to see the grime on the ghost's life. We start to get tangled into the complexity of the problem. And all of that while bouncing quickly through a potboiler set all over the world. There are some minor issues. Occasionally the author loved the words she had written and lost track of their purpose in the story. Far too long on descriptive scenery for no purpose. It is very hard to cut a piece of writing you are especially fond of. But it made the waters muddy instead of brighter. But it did not stop me from enjoying the book. And I would recommend it. It was very enjoyable.
