What is the secret of Granny's wonderful old dolls' house?

Everything is going wrong for Lucy. Dad is losing his job, and the family will have to move into a tiny flat, far away from her best friend, Jessica. Granny's house needs to be sold when she moves into a care home - and worst of all, Granny's dolls' house must also be sold.

But Granny has given Lucy a ring, telling her that it is magic. Jessica and Lucy are determined to find a way to put things right. Could the ring really help - or make matters worse?
