Inspired by Tim Minchin's hit song 'When I Grow Up' from 'Matilda. The Musical', the book takes a humorous yet moving look at adult life from a child's perspective. Grown-ups surely have all the fun as they must eat sweets every day, climb the biggest trees and watch cartoons till their eyes go square. But do they really...? 4+ Hugely exciting picture book collaboration by celebrated musician-comedian Tim Minchin.
