The moment an asteroid hit the Moon and knocked it out of orbit, the life of sixteen-year-old Miranda changed completely. Now the Moon is frighteningly close, so huge, gray and cold... How to survive when huge tsunamis wipe out entire cities and countries , earthquakes shake continents, volcanic ash blocks out the sun, and a mosquito bite can be fatal? As summer turns to arctic winter, Miranda, her brothers and her mother hide in the relative safety of a house where the only source of heat is a wood stove, water is limited, and supplies there may not be enough food for everyone...Miranda describes every day of this new and frighteningly unknown life in her diary.
