During the colder months, some folks like to read about tropical climates and warm days. I have a tendency to want to read about places that are even colder than where I am.
Enter my obsession over books about Antarctica. I don't know that I'll ever get to visit there, but I do love to read about it, both in fiction and nonfiction. While there is a vast body of literature about Antarctic explorers such as Amundsen, Shackleton, and Scott, my reading about the cold continent tends to be about modern folks--scientists and other curious types--who have recorded their time there and are often studying the (few) animals that live there, along with other studies including climate change, the earth's history, and even the possibilities of life on Mars.
