#1 New York Times bestselling author Mark Oshiro (The Sun and the Star) returns to YA with their unique spin on both the horror and dystopian genres, perfect for fans of Andrew Joseph White, Lamar Giles, and Annihilation.

Arturo Ruiz merely wanted to complete his chaotic senior year of high school. But now that the entities have arrived, he'll have to focus on survival first.

The entities don't speak. Don't interact. They watch, hiding just out of sight, observing first Arturo, then his sister, then his friends.

And when they finally invade Arturo's home, his parents sit him and his sister down, and they have a message:

We won't be here when it ends.

They answer no more questions. They walk out of the house, leaving behind not just a deepening mystery, but a horror that will upend how Arturo comes to understand both the world and himself.
