Daniel Kalla is the absolute master of medical thrillers. Fit To Die is about an epidemic of 'weight-loss' pills that are rapidly killing those who struggle with eating disorders and body builders. While this book won't top my favourites list of Kalla's work, it was still very thrilling, terrifying in the sense that it could easily be real life, and so well written. I will say that there were far too many characters to keep up with in this one, I don't even really know who exactly the main characters were supposed to be and I couldn't remember half the names after they were initially introduced. 

Thank you to Simon and Schuster and Daniel Kalla for my copy of this book! For thriller lovers who especially love detective work, medical components and a touch of potential reality - check this book out!
