'In a change to our scheduled programme tonight, I proudly present, for your joy and delight . . .' (in the glare of the bulbs, Ava tipped her tall hat) 'AMAZING AVA! AAAAAAND . . HER INVISIBLE CAT!'

Ava and Squishy are going to see the circus, but when one of the acts doesn't turn up they must perform in his place!

Another joyful, hilarious, instant classic of a tale for five year olds and upwards, stunningly illustrated by Ella Okstad.
