The Buried Giant by Kazuo Ishiguro
Elderly Britons Axl and Beatrice are a devoted couple who decide to leave their cave dwelling to go on a journey to visit their son in another village. Why leave now? Beatrice is clearly upset at losing the privilege of a candle in their room at night, and would like advice for a pain in her side. We gradually learn that there is a mist of forgetfulness throughout the land. What secrets are Axl and Beatrice forgetting, and is there a valid reason for the mist? Axl begins to worry that Beatrice will stop loving him if she remembers their past, and they both wonder if their long-lost son will welcome their visit. Traveling slowly, they encounter wonders, terrors, and adventures, but the pacing never increases in this dreamlike fable for grown-ups, set in the fifth or sixth century, decades after the death of Arthur, a leader of the Britons. There is an uneasy peace between the Celtic Britons and the Saxon invaders. In a Saxon village, Axl and Beatrice hear of a boy stolen by ogres. Edwin is rescued by Wistan, and the four journey together for a while. Wistan, a Saxon warrior, is determined to find and slay the dragon Querig, but elderly knight Gawain claims that quest for himself. A leisurely read, this is a beautiful portrait of an elderly couple and their quest to remember their past, no matter what happens.
