What Doesn’t Kill You

This is an okay book written by Iris Johansen. Catherine Ling was abandoned on the streets of Hong Kong at age four. Schooled in the art of survival, she traded in the only commodity she had: information. As a teenager, she came under the tutelage of a mysterious man known only as Hu Chang – a skilled assassin and master poisoner. As a young woman, she was recruited by the CIA and now she is known as one of their most effective operatives. Having lived life in the shadows, Catherine is aware of the wobbly moral compass of her existence and even more aware of just how expendable she is to those she deals with.
