Fourteen-year-old Madeleine of Cambridge, England, struggling to cope with poverty and her mother's illness, and fifteen-year-old Elliot of the Kingdom of Cello in a parallel world where colors are villainous and his father is missing, begin exchanging notes through a crack between their worlds and find they can be of great help to each other.

In Cambridge, England, Madeleine Tully is still working to gather the Royal Family, and get them back to their parallel world--but in Cello, Elliot Baranski is being held captive, the Hostiles are working against the Royal Family, and the World Severance Unit is trying to stop all contact between Cello and the World for good.
