The granny project - Anne Fine

'What does he mean? What's going on? Are you two thinking of putting Granny into a Home?'
'Thinking is finished,' Natasha told him. 'It is decided.'

She's a bit of a dotty old lady - sometimes demanding, often annoying - but as much a part of their lives as their shambly house or the whirring of the washing machine.
So they decide to take action. They begin 'The Granny Project', with immediate and sensational results . . .
