Shiv's best mate, her brother Declan, is dead. It's been all over the news. Consumed by grief and guilt, she agrees to become an inpatient at the Korsakoff Clinic. There she meets Mikey. Caron. The others. They share a similar torment. And there, subjected to the clinic's unconventional therapy, they must face what they can't bear to see. Shiv is flooded with flashbacks, nightmares, haunting visions of Declan on their last, fateful family vacation in Greece. And with memories of Nikos, the beautiful young man on the tour boat. It started there, with him, beside the glittering sea . . . the beginning of the end.
