Emily recommends: Hellhound on His Trail: The Stalking of Martin Luther King, Jr. and the International Hunt for His Assassin, by Hampton Sides

More than a gripping nonfiction account of the time leading up to the assassination of MLK, Jr., this book is the story of two men at opposite ends of the moral spectrum, and the horrifying moment when their lives intersect. It is also the portrait of a nation in turmoil, many of its people willing to die for necessary change, some of its people willing to kill to prevent change.
Suspensefully told, this narrative gives the reader a clear picture of the U.S. in 1968, from the Johnson White House to the Hoover FBI to the Civil Rights Movement and its leadership. The description of the hunt for King’s killer is compelling; the book reads like an educational novel, and I recommend it highly.
