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.
