A teenage girl and her brother fight for their family’s future in a world devastated by climate change: “Thrillingly scary . . . There is much here to enjoy” (The Washington Post).

In a dystopian future brought about by global warming, seventeen-year-old Nat and her hacker brother, Sam, have come by ship to the Big Island of Hawaii for their parents’ Final Week. The few Americans who still live well also live long—so long that older adults bow out not by natural means but by buying death contracts from the corporates who now run the disintegrating society, keeping the people happy through a constant diet of “pharma.”

Nat’s family is spending their pharma-guided last week at a luxury resort complex called the Twilight Island Acropolis. Deeply conflicted about her parents’ decision, Nat spends her time keeping a record of everything her family does in the company-supplied diary that came in the hotel’s care package. While Nat attempts to come to terms with her impending parentless future, Sam begins to discover cracks in the corporates’ agenda—and eventually rebels against the company his parents have hired to handle their last days. Now Nat will have to choose a side, in this moving and suspenseful novel by a National Book Award–nominated author.
