In this book, the Doctor and Martha are heading off for a vacation, but instead of the beach they end up in an arctic climate, which turns out to be a giant "snowglobe" where antarctic ice has been preserved against loss by environmental conditions. But buried inside the ice is an alien menace that nobody counted on. The doctor and Martha not only have to fight the creature, but also the corporate trying to turn the snowglobes into a jet-setter playground. This was a good, quick read if you like Doctor Who. ( )
