Worth reading! Several years have passed since Book 2 (A Quantum Murder), the major characters and European countries are settling down, now that the worst ravages of global warming are past. People are adapting, technology is advancing, the social situation and economy are recovering from the chaos accompanying massive climate change. In addition to the excellent descriptions of futuristic technology, we get a view of society, economics and politics in a not so pretty future. Underneath the intrigue and fast moving plot is the question of what constitutes a person when minds can be stored digitally, and bodies can be cloned.
