Class brain Bindy Mackenzie has alienated her entire high school but when she realizes someone is trying to kill her, she has to make friends in order to get help.

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.

While Madeline works to gather the Royal Family and get them back to their parallel world, Elliot works to escape the Hostile compound where he's being held captive.
