My parents knew that, for one day, our two-square-mile campground would be the only patch of land in the entire country to lie smack dab in the path of the Great Eclipse when it passes overhead. In precisely twenty-two days and some hours from now, the sun will get erased from the sky, the planets will come out to greet us, the birds will stop singing, and a glowing halo of light will flutter like angels' wings above our heads. Except, of course, if it rains.
