Description:

Katy's gran is 90 years old today. That's quite old. Katy wants to bake her a cake, but can she keep it a secret?

Clare Sudbery is a writer and storyteller who lives with her 5-yr-old son Felix and his dad. They bake a lot of cakes, some of them secret. Felix's great-gran is 93 years old. That's quite old, too.

Lynda Mangoro is an artist and illustrator living in Worthing, England. She can draw cakes better than she can bake them, but her sons Samuel, Jacob and Oliver think she should just practise more.
