This book was very interesting. I was curious about the letter and kind of figured the gist of it by then but it's funny how that impacted so many other people's lives. 
 The book was alright. The different 'what if' scenarios depending on the secret and how different our lives can be was interesting. Not sure I liked the outcome. it was like the secret led to nothing but everything happening. It was like it impacted so many lives but didn't have an outcome or solution to it.
