Armed with trust funds and pedigrees but bent on rebellion, twenty-somethings Alice, Harry, Rose, and Hugo are teetering on the brink of self-destruction. With Manhattan and London as their playgrounds, they chase oblivion—and their next high—through a glittering blur of nightclubs, decadent parties, high fashion, and underground music scenes, hard-partying on the razor's edge with a never-ending cocktail of drugs and booze. Insomniacs and unstoppable, these four lost souls ride the extreme highs and devastating lows of a summer that quickly reaches a crescendo of music, heat, and hedonism. Wavering between moments of revelation and ruin, they illuminate a generation given everything—except an answer to the timeless question: Who am I? From a remarkable new literary voice comes a startling, fresh, strikingly candid novel of addiction and excess.
