Robert Moore, whose African American identity today may be questioned by some because of his very light skin color, grew up in an all-white suburb of Philadelphia in the 1960s when the push to assimilate was blatant. An examination of the life experiences of people sometimes felt to be at the perimeter, serves to point out that the racial categories of White and Black in America remain strong and impenetrable. The book spans nearly fifty years beginning in the author's youth to a contemporary period when he is a sociology teacher in a university classroom.
