In September 1963, the Sixteenth Street Baptist Church in Birmingham, Alabama, was bombed. Four young girls were killed that night, and it is their four spirits that bind the various characters in this book together, by appearing to them every now and again.
This book is primarily a depiction of the turmoil of the 1960s and the racism of the era in Alabama. Characters who experience the presence of the four spirits include Cat Cartwright, a young, wheelchair-bound white woman who makes a metaphorical stand against racism. Christine Taylor is a black college student and single mother who is making a difference with her civil rights work. Real historical figures, such as Dr. Martin Luther King Jr., make cameo appearances.
In the fight against racism, this was an era of demonstrations and unjust jailing of social justice warriors, among many other atrocities. Four Spirits is a story of that era.
