Mummy and Lila are going to visit Grandpa, but Lila is busy in her own imaginative world. Whenever Mummy asks her what she is doing, she always says, "Nothing!" Only the reader is allowed in to her colourful, crazy, creative world where she is wrestling an octopus, or racing along in a winged chariot, or flying with birds over a noisy jungle.

But Grandpa has a plan to join Lila in her secret world. After all, playing is even more fun when you play together!

Bursting with energy and colour, this is a joyous celebration of the imagination and creativity that will speak to child and adult alike.
