Life as we knew it

When Miranda first heard the warnings that a meteor is headed on a collision path with the moon, they just sound like an excuse for extra homework assignments. But her disbelief turns into fear in a split second as the entire work witnesses a lunar impact that knocks the moon closer in orbit, catastrophically altering the earth's climate. Everything else in Miranda's life fades away as supermarkets run out of food, gas goes up to more than ten dollars a gallon, and school is closed indefinitely.
I'd like to give credit to Susan Pfeffer for this book, it's truly extraordinary.
