It's almost Christmas Eve and the rockets on Mr Claus's sleigh have exploded! With just hours to go, Mr Claus sets out to find a creature that can help him deliver Christmas gifts across the world.

The polar bears are strong, but they're too sleepy. The narwhals are fast, but the presents get too wet. The reindeer might just be the perfect creature to help... especially when Mr Claus discovers that the females have a secret... they can fly!

Illustrated by Kasia Nowowiejska, this charming picture book was inspired by the little known fact that Santa Claus's reindeer are female, as only female reindeer keep their antlers during the winter!
