This is a 3.5 star. 
 The poor are not given importance in life or death. Sad but true. Eve comes across a case of a brew-head and she is not one to let anything go without solving it. This novel combines so many interesting things (view spoiler)[ the medical side which I loved reading, the evolution of science, the cop who harasses Eve which was really interesting to read and the story spans continents and timelines. There will always be someone who envies you and wishes you ill luck even if you haven't done any harm to that person. (hide spoiler)] We also come to know why the badge is so important to Eve. There are also glimpses into her past which is really difficult to read just due to the sheer horror of it.
