Seventeen-year-old Blythe Warren attends a private STEM academy run by a mysterious medical technology company where constant security cameras monitor everything. close friend, Gabrielle, suddenly has a public breakdown in class, screaming that the security cameras are always watching her. Blythe finds Gabrielle covered in blood next to a deceased school official, but Blythe's own memory then blanks, replaced by a false memory of slipping on a bathroom floor. As Blythe and her tight-knit group of friends (including siblings Tucker and Tanya) experience violent nightmares and memory gaps, they realize their entire lives and memories might be artificial constructs. Their pasts weren't actually erased—just walled up—and the truth threatens to come out.
