This book provides an eye-opening look at the historical roots of racism in America. Author Jason Reynolds takes great pains at the very beginning to stress that this is not a history book, or at least not in the traditional sense. Rather, his intent is to provide accessible background information drawn from historical context so that teens can understand how ingrained misconceptions regarding the supposed inferiority of the black race and the alleged superiority of the white race first got started in America, and how these myths were spread by powerful people to support their own ends. Well-known historical luminaries ranging from Aristotle to Angela Davis are discussed within the context of their views on racial inequalities. This sounds like pretty heavy content, and it is, but the text is written in a breezy, engaging style which effectively exposes glaring misapprehensions and torpedoes flawed assertions. Lists and recaps help readers keep track of evolving concepts, and popular culture terms and allusions keep the material relevant and fresh. Back matter includes source notes and suggestions for further reading, which make this a helpful resource for research and inquiry projects. Whether used as curriculum support or as a leisure reading selection, this engaging overview offers readers lots to think about and should spark important conversations about this timely topic.
