The Ninth Legion marched into the mists of northern Britain-and they were never seen again. Four thousand men disappeared and their eagle standard was lost. It's a mystery that's never been solved, until now ...Marcus has to find out what happened to his father, who led the legion. So he sets out into the unknown, on a quest so dangerous that nobody expects him to return. This gripping epic set against the backdrop of Roman Britain has been a firm favourite with children and adults alike for over fifty years and is now the subject of a major film. This edition, with its movie tie-in cover, is being published to coincide with the film's UK release.
