Sometimes at the darkest hour, hope shines the brightest... When Col's childhood imaginary friends come to life, he discovers a world where myths and legends are real. Accompanied by his guardians - a six-foot tiger, a badger in a waistcoat and a miniature knight - Col must race to Blitz-bombed London to save his sister. But there are darker forces at work, even than the Nazi bombings. Soon Col is pursued by the terrifying Midwinter King, who is determined to bring an eternal darkness down over everything.
