The memory key

Lately Lily’s grandad has been forgetting things you couldn’t imagine forgetting like what you had for breakfast or how to get dressed. Mum wants to move Grandad to a care home, but Lily just knows that if she can help Grandad find his memory then he’ll be back to normal. When Grandad’s toy train comes to life, Lily and Grandad jump on board and revisit his childhood in Hungary. Then they come to a tunnel that Grandad is scared of and Lily knows going through it is the key to making him better. But not all memories are good and danger lurks in the dark. As Grandad’s memories scatter in the wind, can they capture them all before they fly away?
