The Other Side of Truth by Beverley Naidoo
After the murder of their mother, twelve-year-old Sade and her younger brother are smuggled out of Nigeria by their journalist father to escape the corrupt military government and growing violence. They are sent to their uncle in London, but when they arrive, he is missing and they are abandoned, passed between foster homes. Their father escapes to England to find them — but he will be sent back to Nigeria unless Sade can find a way to tell the world what happened to her family.
