A remarkable story about love and death from the winner of the Guardian Children's Fiction Prize

Eleven-year-old Mouse is travelling to see his grandparents on Christmas Eve with his mother and two sisters. But it's snowing, and visibility is bad, and the car goes off the road, and crashes.

Mouse is thrown from the car.

When he wakes, he's not in his world any more. He meets a sheep named Bar, who can only say Baaa, and a sarcastic horse named Nonky, who is a surprising mix of his beloved toy horse and his older sister.

So begins a quest to find a castle in 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.

But why are they looking for a castle? As the cold grows, we realise it might just have something to do with the family he's left behind; and that Mouse's quest is more important than ever.

This is a novel about love and death. It's about the power of stories to change the way we view the world - and it's about the power of a child to change their own world. Emotionally arresting but ultimately uplifting, this is a remarkable novel for our times.
