Six Wakes (2017) is a novel about a puzzling multiple murder, but also a great speculation about a society in which cloning is legally -and illegally- possible (not spoilers here, this is seen in the firsts pages).
Precisely, one of the strengths of the novel is some brilliant ideas about cloning, but I also consider that the worldbuilding is good, for example inside the starship. We will see that the cloning technology has also other interesting applications such as the Pig-Maker: a large foodprinter, which can produce an entire pig.
The characters are well developed and in a plausible way they show how to being a clone can transform the human psychology. And there is also an artificial inteligence, and by the way: she is a real nuisance.
As a criticism, I must say that the third part of the book is a bit confusing because the plot is so convoluted, but at the end all is explained.
I consider Six Wakes a very good reading, with elements of a classic mistery novel (multiple suspects, secrets, surprising twists) and also a very interesting part of scientific and social especulation.
