Beyond the Wall : Walker Books Ltd : 9781406366273 : 1406366277 : 06 Apr 2017 : The story of a runaway slave girl and her dangerous journey through the murky underworld of Roman Britain, by Carnegie Medal-winning author Tanya Landman. From Tanya Landman, author of the 2015 Carnegie Medal winner Buffalo Soldier, comes a heart-stopping tale of love, corruption and the power of choice. Blood on her lips. Blood on her tongue. Blood that is not her own. Cassia does not fear to die, but for her - for a slave who has maimed her master - there are worse things than death. Yet the mighty Roman Empire has its limits. Beyond her master's estate, beyond the river, far to the north stands Hadrian's Wall. And beyond the wall? Freedom. With dogs on her trail and a bounty on her head the journey seems impossible. But then Cassia meets Marcus - slick, slippery, silver-tongued - a true and perfect son of Rome. And her only hope.
