Eleven-year-old Ophelia might t be brave, but she certainly is curious. Her family is still reeling from her mother's death, and in a bid to cheer everyone up, her father has taken a job at an ermous gothic museum in a city where it never stops swing. Ophelia can't wait to explore and quickly discovers an impossibility. In a forgotten room, down a dark corridor, she finds a boy, who says he's been imprisoned for 303 years by an evil Sw Queen who has a clock that is ticking down towards the end of the world. A sensible girl like Ophelia doesn't quite believe him, but there's denying he needs her help. Ghosts, wolves, misery birds, magical swords - and even fabled Sw Queens - do their very best to stop Ophelia. She will have to garner all her courage, strength and cleverness if she is to rescue this most Marvellous Boy.
