When her sister Gemma is taken into hospital, Miranda escapes into her own fantasy land, Magnanimous. With giraffe police, ham sandwich trees and a Crystal-Clear Glass Hospital for Getting-Better Children, Magnanimous grows and grows.

As her sister gets worse, things Miranda writes seem to trigger small miracles she has been asking for: her gran stops smoking, horrible Darren Hoey is nice to her ... Can Miranda write a miracle for her sister?

'I love Miranda and so will you.'  Eoin Colfer, author of Artemis Fowl
