There is a little door in Kate's pretty new room that she finds worrying. Her parents say it leads to the attic, but she thinks 'things' can come through it. In the night they do - slithery things, fierce animals, and giants. Mum and dad say, 'If you can think them up, then you can think them out' - which she does. Then she thinks up some friendly creatures to be company in the night. A superb combination of text and illustrations.
