I really like this book. I like how it made me think and it had really made me imagine the things she went through. After I was done reading the book, it made me think twice of my life and the quote she put at the end "I have yet to discover all the effects on the Earth of the comet's passing. It's very hard to get any information these days, especially if it has to cross the oceans. People should probably have another 4,000 years to rebuild civilization before Ryan's Comet returns. But then what? The world is filled with dangers of its own. And we humans can invent more ways to destroy ourselves than the ancients would ever imagine. Will we finally learn from our mistakes? I certainly hope so. Or when the comet returns, we may have already destroyed the world ourselves."
