This World We Live In by Susan Beth Pfeffer

After a catastrophic change in the heavens upends climate and civilization, a teenage narrator and the people she loves fight to survive amid food shortages, disease, and the constant threat of violence; journallike entries trace the slow erosion of normal life, the devastating losses they endure, and the hard-won bonds and small acts of kindness that sustain them. The story is a raw coming-of-age and survival tale, focused on family, grief, and the pragmatic choices that keep people alive when the world they knew has been irrevocably altered.
