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 is a tour de force from acclaimed author Adam Silvera, whose debut, More Happy Than Not, the New York Times called "profound."
