Adam Silvera will revisit the world of his most popular YA book in a new novel, HarperCollins Children’s Books announced in a news release.

The press will publish Silvera’s The Survivor Wants To Die at the End in the spring. It will be the third book in the series that began in 2017 with They Both Die at the End and continued in 2022 with a prequel, The First To Die at the End.

The two young adult novels by Silvera tell the story of people whose lives are affected by Death-Cast, a service that calls people on the day they are scheduled to die. They Both Die at the End became a viral sensation on TikTok during the Covid-19 pandemic and is being adapted as a Netflix series.

The Survivor Wants To Die at the End will follow two young men, one the conflicted heir to the Death-Cast fortune, and the other struggling with suicidal ideation, who are brought together by chance.

Silvera announced the new book in a video on Instagram, saying, “It is definitely a novel about ‘self-unaliving’ ideation, which is something that I’ve struggled with for more than half my life.…Neither of these boys will ‘unalive’ themselves at the end of this novel. It is absolutely about battling mental illness, but it is not about dying, it is about wanting to die.”

The Survivor Wants To Die at the End is scheduled for publication on May 6.
