We first meet an old couple in a village, Axl and Beatrice, who are plagued by fading memories of the past and become aware of this fact. After speaking with an old woman, Beatrice persuades her husband Axl, to accompany her on a journey to see their son. When weary, they pause to rest at a Saxon village which is experiencing a commotion. Their host suggests the mist that permeates the air rendering the memories of everyone into fragments could be the work of a God who felt regret. When the couple sets off the next morning to a hillside monastery to consult an old monk, they have two companions who are fugitives foisted on them: Wistan, a skilled warrior and a boy with a suspicious wound, Edwin. Strangely enough the warrior appears to recognise Axl. This unexpected addition to their party makes their journey a less peaceful one.
Once they bump into a character from British folklore charged with a strange duty he never accomplished for which he is maligned, the true mission of the Saxon warrior comes to light. Their stay at the monastery puts the old couple at risk but a friend they made comes to their aid and the two parties are split up. The mission the warrior is charged with is also one the couple promise to undertake when some children mistake them as Elders sent by God and request it so their parents may return to them. While the quest is accomplished, the results of it are going to disturb the peace once maintained by the enforced mist.
The couple faces several dangers, including those who seek to separate them from each other, but it appears Axl has far more to fear from the memories of the past returning than Beatrice. While I didn’t like the fantasy elements incorporated into this and the strange ending, what I did enjoy was how The Buried Giant explored memory: what we choose to remember and what we choose to forget.
