Atkinson’s Life After Life was the wonderful story of Ursula Todd, who kept repeating her life, dying in different ways each time. One interpretation or explanation for this strange experience is that she was trying to create (or find, or reach) a version of her life in which her beloved brother Teddy survives the Second World War and lives to grow old.
A God in Ruins is the story of that timeline.
Or maybe a couple of timelines. While this is in most ways a more straightforward tale than its predecessor, we do see two or three possible different endings for Teddy. It’s also about his descendants: his daughter the infuriating Viola, and her two children. It’s kind of a redemption tale for some characters.
I enjoyed the bits about Teddy’s wartime expreiences as a bomber pilot most. Overall it’s not as good as Life After Life, but not bad.
