Miranda is going about her normal day-to-day. Homework, school, life. There is buzz in the air about an asteroid colliding with the moon. Shouldn't be a big deal other than a pretty light show. Loads of asteroids have crashed into the moon; that's why it has craters. Except it is a big deal. The asteroid knocks the moon off-kilter. This changes everything.I read this book in one sitting. It was so scary because it's something that actually could happen. At least it seemed so in the book. Excellent read.
