The Eye of the Viking God by Terry Deary - old paperback

Age :7-11

The slave girl doesn't even have a name. The bullying Vikings call her 'Fleece' because they make her look after the sheep. She works hard all day, and at night she must serve them food and wine. When an accident happens, and the Vikings have to bury their warrior chief, it looks like Fleece will have the most difficult job of her life.
