Reichs follows up his Virals series with a new fast-moving tale about the final moments of a pre-apocalyptic world as seen through the eyes of two teens living in an isolated Idaho town. Every two years, on her birthday, Min Wilder is murdered by a strange man. But hours later, she wakes up alone, unhurt, and with no memory of the horrifying crime. On her sixteenth birthday Min resolves to put an end to the violent cycle. She joins forces with her classmate Noah who is having the same strange experiences. Together they uncover a vast sinister conspiracy involving the entire sophomore class. Meanwhile the planet is facing a bigger challenge because an asteroid, the Anvil, is headed toward Earth threatening total annihilation.
