Life As We Knew It, by Susan Beth PfefferRead about another entry on the list.
The moon exists in perfect balance with our planet; although it is drifting away in microscopic increments, if it were much closer, its gravitational effects here on Earth would be catastrophic. In Pfeffer’s Last Survivors series, an asteroid hits the moon and pushes it into closer orbit. The resulting tsunamis, volcanic activity, and lowered temperatures send us into a death spiral, as food shortages, disease, and mass casualties unravel civilization itself. The narrator is 16-year old Miranda, who describes the tribulations of her family’s quest for survival in a quiet town in Northeastern Pennsylvania. The story reminds us that our existence is an incredibly lucky one—and incredibly fragile.
