Showing The Garbage King by Elizabeth Laird

Dani and Mamo should never have met. In Ethiopia's great capital city, they have led unbelieveably different lives. Dani's home is a grand house full of servants - Mamo has no home at all. But now both boys are on the run, one fleeing a tyrannical father, the other escaping a life of slave labour. Fate has brought them together, and their only chance of survival is to trust each other with their lives.
