The entire They Both Die at the End series is based on the premise that technology was developed in 2010 that can predict a person’s death day. Those “on deck” to die on any given day are known as “Deckers.” Because Death-Cast is 100% accurate, an entire industry springs up to cater to Deckers. The Last Friend app connects people who don’t want to spend their last day alone with other Deckers or non-Decker volunteers.
The three novels that currently comprise the series all tell the stories of Deckers and survivors. Some of the same characters appear in more than one book, while those who have died are also referenced in relation to other characters. A brief synopsis of each novel is given below to make it easier to understand how each book intertwines with the others.
They Both Die at the End takes place in 2017, three years before the events of the most recent novel in the series. It follows the last day of two Deckers named Mateo Torrez and Rufus Emeterio. They meet through the Last Friend app and decide to spend their final day together. Through their various adventures and shared conversations about their lives, the boys develop strong feelings for each other.
