It is a gift we did here with Ben Goldacre allowing a simple book, well written and clearly know the reasons of the scandals that surround this industry. He manages to avoid the usual weaknesses of the genre, namely a moralizing discourses which have a door pasture actor without even the entire problem.
If you are interested in a minimum this issue, and you are definitely reading this, this book is a must read.
The only flaw, it is not yet translated into French but it is largely the effort.
