Seventeen-year-old Nat and her hacker brother Sam have come to Hawaii for their parents' Final Week. Global warming has devastated the planet, and the disintegrating society that remains is run by "corporates" who keep the population complacent through a constant diet of "pharma." The few Americans who still live well also live long -- so long that older adults, like Nat's parents, bow out not by natural means but by buying death contracts. While Nat grapples with the bizarre ritual of her parents' slickly engineered last days, Sam begins to uncover a secret, wilder Hawaii hidden beneath the high-gloss corporate veneer. Their family's Final Week races toward its climax in the face of a looming hurricane as Nat struggles to protect herself and the people she loves -- along the way forging her own surprising path to hope.
