These concluding years of the freedom era show King at the height of his powers even as his worldly prestige falls under withering attack. We witness non-violent advances for democracy in the face of growing factionalism and fear. We meet heroines and martyrs; enter a world battered by private doubts, public dreams, contagious inspiration, official harassment, and poisonous discord over the Vietnam War. The narrative begins with violence before the pivotal 1965 Selma march for the right to vote, a dangerous time. From landmark victory there, King's movement comes under threat from competing forces. Branch chronicles dramatic campaigns in Mississippi and Alabama, King's tormented alliance with Lyndon Johnson, his painful break with Stokey Carmichael over black power, and persecution by Hoover's FBI. Like Parting the Waters and Pillar of Fire, At Canaan's Edge is a magnificent achievement that brings the decades of the Civil Rights struggle alive and preserves the integrity of those who marched and died.
