De León dismantles the simplistic 'villain' narrative often attributed to smugglers. He delves into the motivations, aspirations, and moral complexities of these individuals, highlighting their humanity amidst a dangerous and often exploitative system. Through the story of one coyote who falls in love and seeks a way out, we see the personal costs and risks associated with this line of work, challenging readers to look beyond stereotypes.

'Soldiers and Kings' goes beyond just the smugglers themselves, exploring the intricate network of individuals involved in the migrant trail. From low-level guides and informants to powerful kingpins, De León maps out the power dynamics and interdependencies within this illicit world. The book exposes the brutal realities of the journey, the constant threat of violence, and the desperation that drives individuals to risk everything for a chance at a better life.

De León doesn't shy away from the larger socio-economic forces that underpin the demand for human smuggling. Political instability, poverty, climate change, and the allure of economic opportunity in wealthier nations create a steady stream of people willing to entrust their lives to smugglers. By illuminating these root causes, the book prompts a critical examination of immigration policies and the global systems that perpetuate this illicit trade.
