Once I got used to the characters in this one I couldn't put the book down. What took me a while was that the main characters - Catherine Ling and Hu Chang - both had sort of strange reactions. I almost had a feeling that they were autistic because of the lack of emotion. Catherine had been on her own in Hong Kong since she was a young child. Her mother was a prostitute who died when Catherine was only four. Another prostitute took her in but there didn't seem to be any emotional attachment. Catherine learned to survive on the shady side of Hong Kong by selling information to anyone who would pay her. When she is fourteen she meets Hu Chang who is an apothecary and doctor of Chinese medicine who is clearly a genius but who also has an odd way of thinking. He determines that the two of them will be friends and he guides her to work with the CIA. He has some interesting morals as he creates and sells poisons among other sorts of potions. Years pass, Catherine joins the CIA, marries, has a child who is kidnapped by a monster when he is two, and has now recovered her eleven year old son. Her son Luke is another character who is extremely bright but has no concept of emotions or attachment. Catherine is determined to protect him and is gradually forging a relationship with him. She gets a call from her CIA boss to tell her that he needs her in Hong Kong again because Hu Chang has created a potion that has made him the target of an extreme villain named Nardik who will do anything to get the potion from Hu Chang.Catherine goes to protect her friend and asks her CIA boss to find someone who knows Mardik. Enter Gallo. Gallo and Catherine have met before and both been attracted to each other. Catherine isn't going to let any possible emotion sidetrack her from her quest and Gallo has his work cut out for him to try to find a place to fit into her life. The most intriguing character in this one is Hu Chang. He is the one who precipitates the actions through his various manipulations. Catherine is often torn between wanting to kill him herself and wanting to protect him. One thing is certain though, Hu Chang always has what he sees as Catherine's best interests in mind as he manipulates those around him. While she loves him, Catherine doesn't agree with many of his choices. There was lots of tension in this one and lots of suspense as Catherine, Gallo, and Hu Chang have to find out who Mardik's intended victim is and to save him. There are chase scenes, kidnapping, fires and other exciting events in this one. I found this one a satisfying way to spend a few hours. It does make me want to look for the other books in which Catherine appears and see her again now that I know her better.
