Really really great. Cora is a first rate badass and my new mantra will be "What would Cora do?"

What made this book really great for me was reading Uncle Tom's Cabin right before reading The Underground Railroad. TUR is both sleeker and huskier. Sleeker because the language is fine tuned to be whip sharp. Huskier because the characters are gritty, grimey, and the violence is bloody and dirty. UTC even says at one point that it doesn't want to offend readers' sensibilities or some such Victorian flooflaw. And in spite of being written in a literary tone, the story keeps moving forward at a very steady pace, never dragging.

Audiobook was perfect too.
