In the not-so-distant future, a company named Death-Cast possesses the mysterious ability to predict death within twenty-four hours. Rufus Emeterio and Mateo Torrez, two young men fated for imminent death, receive their morbid alerts from Death-Cast. Strangers to one another and searching for connection in their final hours, they link up through the Last Friend app. Together, they plunge into a poignant journey, a 'lifetime in a single day,' exploring what it means to live truly and deeply in the shadow of inevitable loss. By leading each other through fear and uncertainty, they discover the preciousness of connection and love, even as their time ticks away. Adam Silvera's 'They Both Die at the End' is an emotional roller coaster that celebrates the transformative power of friendship and the profound impact of a single day.
