One part adventure journalism and one part natural history, Underland is a deep dive into the spiritual significance, historical usage, and environmental importance of the underground spaces of our planet. This book is chock full of thrilling adventures in claustrophobic caverns, slippery sewers, and treacherous mine tunnels. It’s also chock full of long conversations with scientists, so… kinda exciting and kinda boring. I am a small part of a small part of a small part. This world is big and full of wonders, and it’s nice to be reminded of that. I bought this book randomly because I thought it would be an easy sci-fi novel but it wasn’t. It was a book about caves and I liked it a lot.
