I read 'American War' a while back, and it's definitely fiction, but what makes it so gripping is how real it feels. The author Omar El Akkad builds this terrifyingly plausible future where America is torn apart by a second civil war, this time over climate change policies. The details are what sell it - the refugee camps, the drone strikes, the way ordinary people get caught in the crossfire. It's not based on any specific historical event, but you can see echoes of real conflicts like Syria or the American Civil War. That's what makes it such a powerful read. If you're into dystopian fiction that feels like it could happen tomorrow, this one's a must-read. I'd pair it with 'The Water Knife' for another take on climate-driven conflicts.
