It's happening: the days are getting shorter, the air is getting colder and each new weather forecast brings the possibility of snow. Winter is upon us. For many Coloradans, this means it's time to break out the skis and snowboards, but for athletically challenged bookworms (read: nerds) like myself, winter provides a great excuse to curl up out of the cold and do one thing: read, read, read. So when many of my friends are headed to the slopes, I'm heading to the couch with a book, a hot beverage and a couple of dogs in tow.
