at the dangerous edge of social justice is a book of profiles on courage on facing prejudice in America. Chapters include: Emmett Till, killed at 14 in 1955; Medgar Evers, killed at 37 in 1963; Malcolm X, killed at 39 in 1965; Martin Luther King, Jr., killed at 39, in 1968, James Byrd Jr. killed at 49 in 1998, Trayvon Martin, killed at 17 in 2012.

Fifty years after Martin Luther King Jr’s I Have a Dream speech, an Epilogue shows dramatically how far America is from being a fully post-racist society: blacks are still twice as likely as whites to live in poverty; twice as likely to be unemployed as whites; the net worth of white families is 22 times greater than black families – and on and on – This is a sad, tragic – and powerful – book.
