Meet Santa's smallest helper: Tiny Reindeer! He doesn't quite fit in, but when a very special letter arrives before Christmas Eve, he embarks on a mission to find his place in the world. Tiny Reindeer just can't find his place in the busy North Pole. Being much smaller than the other reindeer, he's not very good at any of the jobs Santa gives him. But when a letter comes from a little girl with a Christmas wish to help keep the memory of her grandfather alive, Tiny knows exactly what he needs to do.

From the author of the Waterstones Children's Prize shortlisted Once Upon a Unicorn Horn comes a beautiful story of friendship and protecting the oceans. Theodore has a little boat and a big passion: collecting fish. He loves nothing better than discovering a new fish for his collection. But one day, he finds something he's never seen before: a tiny creature in a beautiful shell. Ignoring the voice that tells him to leave her alone, he takes her home, but in a tank she gets weaker and weaker. Can Theodore learn that the creature belongs in the ocean, before it's too late? This heart-warming story about how mermaids got their tails is the follow-up to the critically acclaimed and best-selling Once Upon A Unicorn Horn and Once Upon a Dragon's Fire.
