On a hot day in July 1919, five black youths went swimming in Lake Michigan, unintentionally floating close to the "white" beach. An angry white man began throwing stones at the boys, striking and killing one.
Racial conflict on the beach erupted into days of urban violence that shook the city of Chicago to its foundations.
A Few Red Drops is "readable, compelling history," The Horn Book wrote, adding that the book uses "meticulously chosen archival photos, documents, newspaper clippings, and quotes from multiple primary sources."
Includes archival photos and prints, source notes, bibliography, and an index.
