Grace rushes home all ready to grab a huge slice of her sticky, spongey, yummy, gooey, creamy rainbow birthday cake, only to discover it has already been eaten! With the help of policeman, Grace discovers a hair that has been left behind but does it belong to her mum, Tiff the cat or her cheeky pug Dax? All she has to do now is use the clue to work out which of the suspects ate her cake. This is an interactive pattern matching exercise for the young reader as they join in with the story to help Grace find the greedy rascal who scoffed her birthday treat. Entertaining and educational, The Missing Birthday Cake is perfect for home, pre-school and early years. It invites children to expand their logical brain and uses colours and forms to encourage their cognitive function. The book also acts as an extremely gentle introduction to the concept of DNA and why that might be useful, thus stimulating an interest in science from an early age. Illustrations are colourful and created in an appealing Disney-like style.
