Nikki Kill has always been an outsider. Born with rare synesthesia, she sees the world differently. In Nikki’s eyes, happiness is pink, sadness is a mixture of brown and green, and lies are gray.

To Nikki, Peyton Hollis, the ultrarich it-girl at school, was seemingly untouchable. That is, until Peyton is violently attacked and the only phone number the hospital finds in Peyton’s cell is Nikki’s. Suddenly Nikki is pulled into Peyton’s glittering, fast-paced world as she tries to unravel an unfolding conspiracy.

As Nikki gets closer to the dark truth-and to Peyton’s gorgeous older brother-the only thing she can be sure of is death is a deep, pulsing crimson.
