Miranda’s disbelief turns to fear in a split second when a meteor knocks the moon closer to the earth. How should her family prepare for the future when worldwide tsunamis wipe out the coasts, earthquakes rock the continents, and volcanic ash blocks out the sun?

Told in journal entries, this is the heart-pounding story of Miranda’s struggle to hold on to the most important resource of all--hope--in an increasingly desperate and unfamiliar world.
