Finished Great Falls by Steve Watkins.
This is a novel about two brothers, one with PTSD after returning from the war. That’s basically all you need to know.
Since he returned, Jeremy’s been different. It’s understandable but Shane wants his brother back. They end up on a camping/canoeing trip together, but it doesn’t seem to be helping. If anything, Jeremy’s getting worse (not sleeping or eating).
This book is painful to read. It goes quickly, but it hurts. And it should. I’m not sure you can have an honest book about this topic if you make it pretty.
