From the review:
As an American, I have a love/hate affair with my country’s history. We’ve done some things we can all be proud of: Kicking some British butt in the revolutionary war, the bill of rights, Batman comics, and the ’85 Chicago Bears (to name a few). But we also have a dark side to our history. One of the first that comes to mind is our history with slavery and the abolitionist movement. It’s hard to believe that there was ever a time where slavery was normal and worth fighting to keep, but we live in different times now, I guess. But this brings us to the theme of our newest review, Freedom: The Underground Railroad. For those not familiar with American history, the Underground Railroad was a system for helping slaves escape their life of bondage to the freedom in the North.
