The Age of Miracles (2012) is beautifully told from the point of view of eleven-year-old Julia. As the Earth's rotation slows, it has unintended and dire consequences for all life on the planet. Meanwhile, Julia is already grappling with all the complexities of being a pre-teen girl, including a crush on a boy, falling out with close friends, and strained relations with her father.
Karen Thompson Walker does an excellent job of putting you in the frame of mind of this young girl, which makes the calamity seem that much more real and heartfelt. Read the ebook or listen to the audiobook on Overdrive.
