The Dead Don't Hurt Us is a story book, where the author imagines two British children are stranded in the Peruvian rainforest after a plane crash. The children survive hardships in the jungle. (I doubt if real UK children could survive in a jungle but it's a work of fiction). They get to witch doctors and cocaine smugglers on the way. Then when the children find a town the authorities persecute them as Street children. The parents of the children struggle to find them and on the way the parents find out about harm oil prospectors and other explorers are doing to the rainforest.
The author has spent years doing medical work in Peru and understands conditions there. The publishers promise that all the proceeds of the book will go to charities that help street children.
