"They Both Die at the End" by Adam Silvera is a young adult novel that follows two teenagers, Mateo and Rufus, who receive a call from Death-Cast informing them that they will die within the next 24 hours. The two strangers meet through an app called Last Friend and spend their last day together, forming a deep connection and reflecting on their lives.
Common Sense Media rates the book as appropriate for ages 14 and up, noting that it contains mature themes such as death, grief, and existential questions. The novel has been praised for its emotional depth and thought-provoking exploration of mortality.
