“With extraordinary tenacity and compassion, Siddharth Kara evokes one of the most dramatic divides between wealth and poverty in the world today. His reporting on how the dangerous, ill-paid labor of Congo children provides a mineral essential to our cellphones will break your heart. I hope policy-makers on every continent will read this book.” — Adam Hochschild, author of King Leopold's Ghost

"Cobalt Red is a riveting, eye-opening, terribly important book that sheds light on a vast ongoing catastrophe. Everyone who uses a smartphone, an electric vehicle, or anything else powered by rechargeable batteries needs to read what Siddharth Kara has uncovered." — Jon Krakauer, author of Into Thin Air

"Meticulously researched and brilliantly written by Siddharth Kara, Cobalt Red documents the frenzied scramble for cobalt and the exploitation of the poorest people in the Democratic Republic of the Congo.”

— Baroness Arminka Helic, House of Lords, UK

"Siddharth Kara's powerfully told and meticulously researched book exposes the dirty secret that much of our 'clean' energy is powered by the violent exploitation, and blood, of children in the Congo. He makes a compelling case for the urgent need to address this modern form of slavery. " — Nick Grono, CEO, Freedom Fund

"As the world continues to embrace the net zero agenda and becomes ever more dependent on personal electronic devices and new technologies, this compelling book paints a dire portrait of the conditions under which a crucial natural resource is extracted. Drawing on multiple field missions and first-hand accounts of the process of cobalt mining in the Democratic Republic of Congo, Siddharth Kara shows in vivid detail not only life on the ground and the true human cost of extraction, but also the gross inequalities built into global value chains and business models that underpin this industry. This account reinforces our understanding of the interdependent and mutually reinforcing nature of all human rights and the many negative externalities of our modern global economy." — Todd Landman, Professor of Political Science, Pro Vice Chancellor of the Faculty of Social Sciences, and Executive Director of the Rights Lab at the University of Nottingham
