No one has yet succeeded in reaching the North Pole, and a new British expedition is mounted. As our protagonist, Adam, returns from the arctic, all the humans and many of the animals he encounters are dead. Adam travels all over the world, looking for other living people and, understandably, going kind of bonkers.
I wanted to like this book more. Early in the book, Adam finds himself in many morally challenging situations, but he has these voices in his head that more or less compel him to act in certain ways, so the reader is prevented from really entering into any moral struggles with him. I liked the writing, but each place Adam goes is essentially like the rest--everyone's dead--and I kept waiting for something interesting to happen. Near the end, something finally did, but then I mostly wanted to slap Adam around for being so dense.
Maybe I'm just jaded from reading too many post-apocalyptic stories and that's why I'm not more enthusiastic about this book. If you're new to this sort of story, you might find this book to be a powerful exploration of loneliness and the meaning of human society and human life. A similar but much better post-apocalyptic novel is Cormac McCarthy's "The Road."
