In the middle of a raging snowstorm, a small white creature arrives at the North Pole. She appears different from any other reindeer in Santa's Village.

Is she a reindeer from a faraway land? A crandeer, half creature, half reindeer?

Or, is she an angel sent from the stars above to put right something that has gone wrong?

It's a mystery that Georgia, Sasha (both Elf Veterinarian Apprentices), and Watson (the newest flying reindeer on Santa's sleigh team) are determined to uncover.
