This scifi book touches on some pretty dark topics like child soldiers, fascism, and eugenics. It has an interesting throughline story and framework that, combined with a lack of gory detail, make it a great way to engage with these topics, for me at least. It mostly takes place on a rebel microplanet as one group of teen soldiers graduates and receives their adult assignments continuing to fight for what amounts to human supremacy. But things don’t go as planned.
