Death/Site. Those That Remain (en Inglés) - Lee Wallace

Continuing in the vein of DEATH/SITE and DEATH/SITE: SECONDS, DEATH/SITE 3.0: THOSE THAT REMAINS is about death, sex, and a family secret that could destroy the very people who keep it.

We live in a simulation. DEATH/SITE is a website that allows us to hack into the simulation and kill those whose contact information we have through a prediction of death. If we predict three people, we're free, but some continue, as they have much more on their deadly list of blood and death and a dark imagination.

When her family killed, she comes to live with another family, whose son she has a crush on. As their romantic feeling blossoms, the mother's resentment flares, and it flares in ways the children couldn't predict and those that knew her, too.
