They Both Die at the End (They Both Die at the End #1) by Adam Silvera

On September 5, a little after midnight, Death-Cast calls Mateo Torrez and Rufus Emeterio to give them some bad news: They’re going to die today.

Mateo and Rufus are total strangers, but, for different reasons, they’re both looking to make a new friend on their End Day. The good news: There’s an app for that. It’s called the Last Friend, and through it, Rufus and Mateo are about to meet up for one last great adventure—to live a lifetime in a single day.

In the tradition of Before I Fall and If I Stay, They Both Die at the End—one of the Best Books of the 21st Century according to Kirkus Reviews—is a mega-bestselling tour de force from acclaimed author Adam Silvera.
