In Traveling Black, Mia Bay’s superb history of mobility and resistance, the question of literal movement becomes a way to understand the civil rights movement writ large…Bay…is an elegant storyteller, laying out the stark stakes at every turn while also showing how discrimination wasn’t just a matter of crushing predictability but often, and more insidiously, a haphazard jumble of risks…Her excellent book deepens our understanding of not just where we are but how we got here.
