I think this has to be one of the weightiest activism books I've read so far. I suggest getting the 20th anniversary edition simply because of all the additions that provide even greater context. 

It took me longer to get through it because the  history provided is so rich and dense. I had to go back and re-read/listen to several parts simply because I found myself getting lost in the history. There is a lot of inspiration to be found in these pages, but I'm actually at a loss of how to even begin to describe this book. I'm still reeling from it. 

I will have to reread it several more times to take in all of the lessons on "the power of imagination to transform society" and all the inspirational freedom dreams discussed in its pages. 

Because if you can't imagine the kind of future you want, you can't even begin to build on it. Like Alice Walker said, "Look closely at the present you are constructing: it should look like the future you are dreaming".
