You've seen your own blood, when you have a cut or a scrape. You can see the veins in your wrist, and you've seen the scab that forms as a cut heals. But do you know what blood does for you? Without blood, you couldn't play, or grow, or learn. That's because just about every part of your body needs blood, from your muscles to your bones to your brain. How does your body use blood?

This vividly rendered Civil War history presents “a lively guided tour of Washington during the 24 hours or so around Lincoln’s swearing-in” (Adam Goodheart, Washington Post). By March 4, 1865, the Civil War had left intractable wounds on the nation. Tens of thousands crowded Washington’s Capitol grounds that day to see Abraham Lincoln take the oath for a second term—and witness what was perhaps the greatest inaugural address in American history. Lincoln stunned the nation by arguing that both sides had been wrong, and that the war’s unimaginable horrors might have been God’s just verdict on the national sin of slavery. In Every Drop of Blood, Edward Achorn reveals the nation’s capital on that momentous day—with its mud, sewage, and saloons, its prostitutes, spies, reporters, social-climbing spouses and power-hungry politicians. Swirling around the complex figure of Lincoln, a host of characters are brought to life, from grievously wounded Union colonel Selden Connor to the embarrassingly drunk new vice president, Andrew Johnson, to poet-journalist Walt Whitman; from soldiers’ advocate Clara Barton and African American leader Frederick Douglass to conflicted actor John Wilkes Booth. In indelible scenes, Achorn captures the frenzy and division in the nation’s capital at this crucial moment in America’s history. His story offers new understanding of our great national crisis, and echoes down the decades to resonate in our own time.
