A heart wrenching, powerful book. Well worth a read. Regardless it's novel status, reading this you know slavery was this bad (or worse). The only part of the book I didn't think really worked was the underground railroad being an actual railroad. Whitehead did not fully explore it as a function - I wish it had been more developed. Regardless his writing is superb. 
 It's important to remember in these times that this is our history and we must own it, acknowledge it, never forget it, and most importantly fight to never let it happen again.
