A boy with synesthesia-a condition that causes him to see colors when he hears sounds-tries to uncover what happened to his beautiful new neighbor-and if he was ultimately responsible. Thirteen-year-old Jasper Wishart lives in a world of dazzling color that no one else can see, least of all his dad. Words, numbers, days of the week, people's voices-everything has its own unique shade. But recently Jasper has been haunted by a color he doesn't like or understand: the color of murder. Convinced he's done something terrible to his neighbor, Bee Larkham, Jasper revisits the events of the last few months to paint the story of their relationship from the very beginning. As he struggles to untangle the knot of untrustworthy memories and colors that will lead him to the truth, it seems that there's someone else out there determined to stop him-at any cost.
