Reddit reviews April 1865: The Month That Saved America (P.S.)

I read Beyond the Deep and Blind Descent over the summer. Both are about supercave exploration, which it turns out is the most terrifying thing on earth. Both are in the same genre as Into Thin Air, another horribly scary book about things I will never ever do. I'd recommend reading Blind Descent first because it's the more general book, while Into the Deep is about one specific exploration. Both are absolutely mandatory reading if you're planning on seeing that new James Cameron movie that comes out in February.

On the history front, April 1865 by Jay Winik is a superb analysis of the last month of the Civil War. Lincoln's Melancholy by Joshua Wolf Shenk is a great analysis of Lincoln's lifelong battle with depression. And Ecological Imperialism by Alfred Crosby is one of the most interesting history books I've read in a long time. This may be a good follow-up to Guns, Germs, and Steel if you're interested in environmental history.
