It takes a lot for me to give 5 stars but this one absolutely deserves it without reservation.  Highly charged storyline with real characters and the medical terminology/descriptions/drug effects are correct, easy for anyone to understand and very well written throughout. I was lucky enough to download this book for free, but quite honestly it is worth paying for- and I say that to very few. If you enjoy a highly charged mystery with a medical/psychological slant and don't want all the pornographic sex bit, this book will not disappoint.
