Just the preface had me hooked, though it took a couple of chapters to grasp what was going on. There are several threads - Laura on an Antarctic expedition; a city peopled by those who are not dead as long as someone living remembers them, and a virus killing off the world's population. The Arctic scenes make you feel cold, the city makes you feel alive, and the massive outbreak of the virus, suspicious. You'll want to keep reading to see how it all hangs together. I can't recommend this book highly enough.
