Six Wakes by Mur Lafferty is a science fiction mystery, one of the finalists for the Hugo Award for the Best Novel category of 2017.
In the future, cloning is commonplace, but its use is strictly limited by law to ensure that it’s only used for longevity of a person rather than multiplication. Every clone makes regular mindmaps of their memories and after they die, a new youthful body is cloned from their DNA and the mindmap copied into it. Many clones have hundreds of years worth of memories they carry with them as though they have lived a single long life. The practice of cloning is not accepted by everyone, especially religious groups, many of which consider clones to be soulless abominations, and there have been violent conflicts about cloning practices.
