Hope is dying. Hope Jackson knows her short life has been a success, but her four closest friends are dangling on the brink of disaster. Right before dying of a rare heart condition, Hope creates a scavenger hunt across New York City using her own graffiti art. The directions she leaves are simple: If her friends can solve the clues hidden in her art, they'll also solve the problems haunting their lives. Hope is dead. Two days after her heart fails, Hope's four friends find themselves thrown together: Kali, her foster sister, whose last ties to sanity are as razor-thin as her anorexic waistline. Erik, her high school crush, whose success as an athlete is based on a lie with no end in sight. Aiden, her best friend, whose plans to become a doctor have been thrown into disarray by his own OCD. And Sam, her online pen-pal, whose perfect life exploded into chaos in the aftermath of a school bombing. Together, the four teens take to the streets of New York to complete Hope's scavenger hunt and fulfill her dying wishes. But in order to unravel the clues hidden in Hope's graffiti, her friends will have to confront their personal demons head on. Hope is within reach.
