One day, when a little girl is playing in her tree house, a unicorn arrives. Keen to help her new friend, the little girl takes the unicorn to visit places around the town which might make a suitable new home. From the pet shop to the fair, together they explore until, at last, the unicorn finds its perfect forever home.

Simply delightful from start to finish, Unicorn Post is a gentle, heart-warming story, perfect for sharing. Children will love lifting the flaps to explore the leaflets and letters which are found throughout the book, enhancing the story with lots of additional details and humour.

These are so delightful that readers are sure to be inspired to create their own little leaflets and letters, perhaps as part of their own book made in this style. The Funfair map includes a key to help identify the different rides and locations whilst the leaflet from the pet shop is full of 'purrfect' puns and and 'cheep' offers!

The illustrations are gorgeous and the whole book has a rosy glow, which adds to the warm feeling of the story. As the little girl tries her best to find the unicorn a home, the relationship between them blossoms until, although happy she has found the perfect place for the unicorn to live, the little girl is deeply saddened to leave her new friend behind, leading to a long walk home with no singing and a grey tinge spreading across the landscape. Fortunately, the perfect happy ending is just round the corner...

Although not many people write and post letters these days, this book reminds us how nice it is to receive something so personal! Unicorn Post is a real joy!

Unicorn Post is another brilliant book from Emma Yarlett. This story is about a young girl who gets an unexpected knock on her treehouse door and finds a Unicorn on her doorstep. The little girl decides the Unicorn must be lost and takes it upon herself to find it a new home - some she suggests are more suitable than others! As the day progresses, the unlikely pair bond and become friends.

I am a big fan of The Post Bag series of books and their interactive features. Within this story, each home for the Unicorn has a leaflet or poster attached, telling us more about its features and bringing the story alive. Books like this are very popular in the reading corner and the children are fully immersed in the stories when they are reading them.

Filled with jokes and colourful illustrations, there is fun for all in Unicorn Post. I am very much looking forward to adding this to our reading corner alongside the others we have in our collection.
