"Celebrated author Carole Boston Weatherford and illustrator Floyd Cooper provide a powerful look at the 1921 Tulsa race massacre, one of the worst incidents of racial violence in our nation's history"-- On May 31 and June 1, 1921, an armed mob looted homes and businesses as Black families fled. The police did nothing to protect Greenwood, and as many as three hundred African Americans were killed, most buried in unmarked graves. Thousands were left homeless. No official investigation occurred until seventy-five years later. Unspeakable helps young readers understand the events of the Tulsa, Oklahoma race massacre, one of the worst incidents of racial violence in our nation's history.-- adapted from jacket.
