By the end of the first page of John Lanchester's book, you know that the eponymous Wall is cold. So one could be forgiven for finding it a bit tedious to continue reading about the cold, the concrete, the sea and sky well into chapter two.The story is narrated by Kavanagh, a new Defender on a two-year posting at the Wall. His mission is to keep the Others from climbing over it. If his unit fails to keep them out, then Kavanagh himself may be banished and cast adrift into the ocean.
