Forty thousand people died trying to cross international borders in the past decade, with the high-profile deaths along the shores of Europe only accounting for half of the grisly total.

Reece Jones argues that these deaths are not exceptional, but rather the result of state attempts to contain populations and control access to resources and opportunities. "We may live in an era of globalization," he writes, "but much of the world is increasingly focused on limiting the free movement of people."

In Violent Borders, Jones crosses the migrant trails of the world, documenting the billions of dollars spent on border security projects and their dire consequences for countless millions. While the poor are restricted by the lottery of birth to slum dwellings in the aftershocks of decolonization, the wealthy travel without constraint, exploiting pools of cheap labor and lax environmental regulations. With the growth of borders and resource enclosures, the deaths of migrants in search of a better life are intimately connected to climate change, environmental degradation, and the growth of global wealth inequality.
