"Essential, bracing, inspiring reading, brimming with fresh and surprising insights and groundbreaking discoveries, many hiding in plain sight but—like whiteness itself—long rendered invisible, requiring a comparative, transnational approach to race studies and the rigor, shrewdness, measure, and skepticism of Emily Weissbourd to reveal them." (Robert B. Hornback, Oglethorpe University) "Bad Blood provides the first meaningful analysis of how literary presentations of blood purity and blackness in Spain were mistranslated in an English context. Emily Weissbourd exhibits an impressive breadth and depth in her engagement with primary and secondary sources." (Christina H. Lee, Princeton University)
