A very good novel in ALL aspects except one horrendous mistake (for me) that is the last enemy that is dual race.
I feel pity for them, they are living on a frozen hell and only want to live in a better environment. But because the author hates to the core the japanese and the dual race are "pictured as japanese" (WW2 sh*t) so they are considered as amoral degenerates and exterminated to the last (Including children and elders).
But I still recommend this novel, one mistake at the end don't destroy the rest of a good novel.
