A review by ichirofakename
Supernova Era by Cixin Liu

2.0

Too slow, thin, misguided, and too few wild ideas, basically nothing wild enough after setup. All adults die, so 13-year olds and younger take over, leading to instant play war, if "play" applies when hundreds of thousands die. Solution is to swap countries and/or move to Mars. There you go.

Of Liu I can only recommend the Three Body Problem, much more science, less sociology. Readd them in order then thank me.
