Madeline, 14, lives in an attic flat in Cambridge and is dealing with sudden (comparative) poverty and her mother’s odd breaks with reality. Elliot, 15, lives in the kingdom of Cello, a world which could seem almost unbearably pleasant and small-town and kind except for its very weird and color-filled edges—colors attack, seasons roam unpredictably. The two teenagers communicate between their worlds. Isaac Newton, color theory, and the laws of physics, of course, are epistolarily discussed as Elliot inserts a letter into a crack in a concrete sculpture on the school grounds in Cello and Madeline sees the corner of white poking out from the foot of a parking meter in Cambridge. Clever, quirky, charming, comic, sad—you know the list, but this is unlike anything else out there. Grades 7–11.
