I forgot what exactly made me pick this up, other than it's a very important story told by one of the (if not THE) pivotal figures of the Montgomery bus boycott. It's not particularly worth rehashing here (since you might as well read it yourself!) but it remains a key moment in history that, unfortunately perhaps, remains topical and important today.
It's a good introduction to the nonviolent struggle plus the planning, logistics, issues, etc. all surrounding how to implement a boycott of this size at this point in history. It was a good reminder that it's a long and often difficult struggle, and sometimes it means scary moments, damage, threats of violence (or actual violence), and more. And in relation to current events, it also served as a contrast: sometimes these types of works do not always get the results the participants want or seek and sometimes can end very badly, as MLK was assassinated eventually.
And while others have mentioned, while it is MLK's work and book and his perspective, it would have been nice to see more of his wife's perspective/thoughts. This is a personal matter, as I had recently read CSK's book so I couldn't help but wonder and think about her role here.
It's not for everyone but certainly I think if you have any interest at all in MLK (no matter HOW you feel about him, positive, negative, etc.) or the concept of nonviolent resistance, this is a good book. Borrowed from the library and that sounds about right for me.
