Just finished reading it the other day, and I will say it was a compelling read.

It gave good insight, albeit in a fictional setting, of a Modern Civil War in the US.

Real emotional at times, had to put it down a few times to stop myself from getting emotionally overwhelmed.

The human suffering, the recurring theme of "brother against brother", and when idealism gets slapped in the face by the realities of war, it is a good book that I would recommend in prepping circles.

I won't give any spoilers, though it does help to at least try to put one's politics to the side and try to read the book from a humanist/love thy neighbor perspective.

If the mods allow it, I am open to discussing the book in the comments.
