Life As We Knew It

Dena suggested this one to me. I couldn't put it down. It's a teen novel, and written as a young girl's diary. An asteroid hit's the moon and knocks it out of it's orbit, which changes the earths tides and magnetic pull. This is the diary of a young girl, living with her mom and 2 brothers, during these events. I won't go into the story, because I would probably give too much away, but.. it's a good story and stays with you.
