There May Be A Castle by Piers Torday

A remarkable story about love, loss and the power of the imagination, from an award-winning, celebrated writer for children.

On a frozen Christmas Eve, Mouse Mallory and his family set off across a snow-white valley to visit his grandparents.

They never arrive.

As the wheels skid off the icy road, Mouse is thrown from the car. When he wakes, he finds himself in a magical landscape, with only a talkative sheep and a very bossy horse for company.

And they tell him: this is your story now.

So begins Mouse's extraordinary quest through a world of wonder. A world of monsters, minstrels, dangerous knights and mysterious wizards; a world of terrifying danger but also more excitement than Mouse has ever known.
