One is an interesting post-apocalyptic novel written by Conrad Williams and released in 2009. The cause of the disaster in One remains a mystery although its effects are devastating and kill most of the people on earth. The main character, Richard Jane, is a deep sea diver that works on oil rigs and happens to be deep under water when the incident occurs. Presumably, the mass of water above him shields him from the devastation. The story follows Richard in his search for his five year old son that was living in London at the time of the disaster. The world that Richard finds is a desolate, dreary place that has become overridden with zombie type creatures that are “stealing” female survivors for some mysterious, horrifying reason. One has an “extraterrestrial” feel to it. It leaves you wondering if the entire incident was some type of an alien attack and that the aliens are intent on reproducing and populating the earth. This was a dark tale of survival. It reminds me of a dream where you decide to fight against what is trying to “get you” even though you know you are going to die. One offers little in the way of practical tips for preparation for disaster but it does provide an interesting and entertaining perspective on the apocalypse.
