The Matilda Effect Paperback / softback

Matilda loves science and inventing. Her heroes are Marie Curie, Leonardo da Vinci and Thomas Edison, and one day she wants to be a famous inventor herself.

So when she doesn’t win the school science fair, she’s devastated – especially as the judges didn’t believe she'd come up with her entry on her own. Because she's a girl. When Matilda shares her woes with her Grandma Joss, she's astonished to learn her grandma was once a scientist herself – an astrophysicist, who discovered her very own planet.

Trouble is, Grandma Joss was also overlooked – her boss, Professor Smocks, stole her discovery for himself. And he's about to be presented with a Nobel Prize. Matilda concocts a plan. They'll crash the award ceremony and tell everyone the truth!

So begins a race against time - and against Matilda's strict mum and dad! - on a journey through Paris, Hamburg and Stockholm, and on which they encounter a famous film star, a circus, and a wanted diamond thief...
