The sun falls out of the sky and onto what is now called The Dome that has encased Earth's atmosphere, shattering the sky as humans know it. A chunk of The Dome falls into the ocean, causing a dramatic sequence of earthquakes, tsunamis, and other natural disasters that have killed off most of the population, and now those remaining are getting strange feedback signals from what appears to be nowhere. Seventeen-year-old Lily and her fourteen-year-old brother Parker are some of the few who have survived. In an earthquake, a pole impaled Parker, and he is mortally wounded, and Lily doesn't know who she can trust. Or what it is that is starting to descend through the hole in the dome.
