The book reveals how our digital revolution's foundation rests upon systematic exploitation in Congolese cobalt mines, where workers face life-threatening conditions and toxic exposure for minimal compensation, all to power our smartphones and electric vehicles.

Kara meticulously traces how major technology companies, despite public commitments to ethical sourcing, continue to benefit from a supply chain that obscures the origins of cobalt and perpetuates human rights abuses through multiple layers of middlemen and willful ignorance.

The author demonstrates how everyday consumers are unknowingly complicit in this humanitarian crisis, while arguing that meaningful change requires both individual awareness and systematic reforms in how we source and utilize critical minerals.
