On 5 September, just after midnight, Mateo Torrez and Rufus Emero receive a phone 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 on a special app called The Last Friend and meet for a great adventure - to live their whole lives in one day. Adam Silvera reminds us that there is no life without death, and no love without loss. This is an inspiring story about people whose lives change in one unforgettable day.
