Mass Extinction Event is a thirteen-book post-apocalyptic series by Amy Cross, published between 2018 and 2020. The series tracks the collapse of civilization through dated installments, from the first days of the catastrophe through an entire year of survival.
The day-by-day structure creates a documentary feel, charting the slow breakdown of society and the increasingly desperate measures taken by survivors. The final installment, Day 365: The Final Day, marks a full year since the world fell apart.
