What would you do if you found out you had one day left to live?

On September 5, just after midnight, Mateo Torres and Rufus Emeterio receive a call from the “Heralds of Death” to tell them the bad news: they will die today. Mateo and Rufus are strangers. They find each other in a special application “Last Friend” and meet for a great adventure - to live a whole life in one day.

Adam Silvera reminds us: there is no life without death, and there is no love without loss. This is a gripping story about people whose lives change in one unforgettable day.
