Trash by Andy Mulligan

Raphael is a dumpsite boy. He spends his days wading through mountains of steaming trash, sifting it, sorting it, breathing it, sleeping next to it. Then one unlucky-lucky day, Raphael’s world turns upside down. A small leather bag falls into his hands. It’s a bag of clues. It’s a bag of hope. It’s a bag that will change everything!
