Keeping Mum

Abbi is in trouble at school: she's always late, or forgetting her homework, or falling asleep in class. When her teachers investigate they discover that Abbi's mother is an alcoholic and Abbi is doing everything at home, - looking after her mum and her younger brother, as well as attending school. After all, if Abbi can't hold it all together, surely the family will be split up. Can Abbi and her mum get help?
