Maia and Nathan recommended this book, and it just took over my whole Friday! I found it absolutely riveting. 
 16-year-old Miranda is a normal, self-centered teen, hoping she'll get asked to the prom, resenting her dad's new wife, when a seemingly innocent event occurs: a meteor hits the moon. But it hits harder than expected, and the moon is pushed closer to the earth, and the effects move from inconvenient (no cell phone service) to downright disastrous (tsunamis, volcanic eruptions, winter in August, flu pandemic). 
 Miranda is lucky to have a resourceful mother, two strong boys in the family, and a house in rural Pennsylvania with a well and a woodstove. This book will keep you reading day-by-day to find out who, if any, of the family will survive as their world shrinks to one room around the fire in a dark house. I can't stop thinking about how much we all have, how precious life is, and how badly off I would be if anything like this really happened. I might just stock up on canned food, bug spray, and thermal underwear. 
 For those who have sought a sci fi book with a girl protagonist, this one's at the top of my list.
