The First To Die At The End by Adam Silvera

Set before the events of the original novel, this prequel follows the aftermath of the very first person to receive a Death-Cast call in a near-future world where a service alerts people on the day they will die; through the perspectives of those connected to that tragedy, it explores how a single notification upends relationships, sparks public debate, and forces characters to confront love, grief, responsibility, and what it means to live when the end has been announced.
