I bought this book after seeing the movie Clint. Initially, I found it very light because I came out of a Jaume Cabré. I started reading in disorder, attracted Inserts photos, especially in reading the parts reserved for Taya, the wife of Chris kyle. I found these passages very moving and I had the idea to go see the head of the murderer Chris. I started to read in the correct order. This is a very hard book. Under apparent ease. Chris Kyle seemed like a force of nature, solid, which can protect anyone but who can not live without the adrenaline of combat. It is factual, there has never pathos or questioned, Chris Kyle is there to kill and to prevent his brothers in arms are killed. It is terrible because for Chris Kyle, skirmishes, ambushes, it's everyday life. I realized that reading at night, I slept very badly then, and I stopped reading this book before the end because it disturbed me too much. I do not imagine what his wife could not bear all this time he had left. And he was killed by a little guy back completely dilapidated it is a very hard book
