This was a low pick for me. I enjoy Dan‘s work but this one made me feel unintelligent sometimes. The consistent NASA level science and political jargon felt cumbersome at times. Amounts of it were very interesting and enjoyable to read/learn but other times I was willing it to be over. I love his short chapters and ability to leave you on a cliffhanger. The thrilling part moved fast and was engaging, it just wasn‘t a fav. #Roll100 for Jan!
