"Lucy Weaver has her future all figured out. Make an appearance at prom, ditch graduation, and then head out on an epic road trip with her boyfriend, Luke. But when everyone's phones start to ring halfway through the dance, Lucy knows something terrible has happened--something big. Decades of climate change have left the world teetering on the brink--entire cities drowned, violent extremism on the rise, millions of refugees with nowhere to turn. Is this the night it finally slips over the edge?"-- Provided by publisher.
