The story takes place in a tomorrow that very well could exist. It's a world exactly like our own. Miranda is a sixteen year old High School student and the world is suddenly buzzing with activity because scientists have found out that an asteroid is going to strike the moon. It's excitement for the research and the amazing opportunities this might present, not fear. But something goes terribly wrong. The asteroid pushed the moon into a closer orbit, throwing of the tides causing mass floods across the world, destroying entire cities. The sudden change of gravity ignites active volcanoes like never before, reignites dormant volcanoes, and opens up entirely new ones. Earthquakes and storms strike the Earth everywhere. Miranda and her family--her Mother and two brothers Jon and Matt--must fight to survive and hang on to what little hope they have of living through the worst catastrophe in human history.
The novel is told in diary entries, as if Miranda were a real person, and this were a real event. It adds delicate reality to the already realistic world Pfeffer has created. Miranda narrates the events as they take place--the cold, the snow, the ash, and the deaths and chaos. Despair seems to creep in everywhere. You get a clear picture immediately of just how terrifying this experience must be and then an idea of just how strong a family relationship must be to allow them to survive.
It's a rich tale, very rich, and one that I am so happy to have read. It's not even really SF. It very well could be a reality. Tomorrow this could happen to our world. Who knows. There isn't some grand scale of technology here. It's reality in a fictional sense. This is a must read novel of suspense, danger, and the power of hope. Pick it up. You won't be disappointed!
