In this prequel to the NO. 1 INTERNATIONAL BESTSELLING phenomenon of TIKTOK fame, They Both Die at the End, two new strangers spend a life-changing day together after Death-Cast make their first fateful calls.

It's the night before Death-Cast goes live, and there's one question on everyone's mind: Can Death-Cast actually predict death, or is it an elaborate hoax? Orion Pagan has waited years for someone to tell him that he's going to die, given his serious heart condition. Valentino Prince has a long and promising future ahead of him and only registered for Death-Cast after his twin sister nearly died in a car accident.

Orion and Valentino cross paths in Times Square and immediately feel a deep connection. But when the first End Day calls go out, their lives are changed for ever - one of them receives a call . . . the other doesn't.
