It is Silvera's third novel and focuses on two teenage boys, Mateo and Rufus, who discover that they only have one day left to live. In April 2020, due to #BookTok, a popular hashtag for readers on social media platform TikTok, the book's popularity saw a resurgence, once again placing it on The New York Times Best Seller list. Plot summary Shortly after midnight on September 5, 2017, Mateo receives a phone call from Death-Cast, a company that rose to prominence seven years prior and is able to predict the deaths of individuals, informing him that he is now a Decker, someone with only twenty-four hours (or less) left to live. Mateo initially intends to spend his End Day in his bedroom but decides to try to push himself to truly live, reluctantly downloading Last Friend, an app developed to help lonely Deckers find someone to spend their End Day with. Rufus is in the middle of beating up Peck, his ex-girlfriend Aimee's new boyfriend, when he received a call from Death-Cast claiming he is going to die in the next 24 hours. His friends Malcolm and Tagoe remind Rufus not to get carried away because of the news. He allows Peck to leave so that he can return to his foster home to say his goodbyes. Rufus, Aimee, Malcolm and Tagoe, collectively known as The Plutos, hold a funeral for Rufus at his foster home but it is interrupted by Peck, who calls the police to have Rufus arrested for assault. Rufus flees and goes on the run, downloading Last Friend so that he won't live out his final day alone.
