I have been following Scott Kelly story for several years now. Every time him and his brother do a mission I am excited to see what they have discovered. When they announced the experiment of sending Scott into space for 1 year then comparing him to his brother when he returns sounded amazing yet terrifying to me! I have seen several news interviews of his journey, but wanted to know more about the emotional process Scott has gone through. He does a wonderful job at descriptions and explaining his experience. He goes into detail about things he has learned and what he did to pass the time in space. We also get to see what happens after he returns. We get to meet several members of his family including his twin brother Mark. This was a fantastic Non-Fiction!
