 I read "Life on the Edge". This book is about unlikely, dangerous, forgotten homes. The first place is Scott Bace in Antarctica. Many kinds of researchers live there. This place is a research center for scientists studying various things like climate change. Antarctica is a very cold and dark place, so it is fun for people who like to spend in the cold and dark. The second place is the International Space Station (ISS). It is 350 kilometers above the Earth. Since it is traveling at 28000 kilometers per hour, it takes only two days to arrive there. The ISS has many things to live such as beds, showers, food, so you can live almost life on earth. However, it is difficult to swallow food because there is not gravity. In this way, you can learn about various strange places.
