"Meet Donald Leroy Samson, an ex-gang Younger from Hackney. Born into poverty, and groomed by violent gangs, Donny's early life was tough. Now, at the age of 15, he's being fostered in the rural safety of Herfordshire. During his Year Ten work experience on the Union Canal, Donny learns that the canal network leads through 29 locks back to Hackney. Determined to meet his mum, who will soon be released from prison for drug offences, Donny 'borrows' a narrowboat to make the journey back to London."--Back cover.
